build: move e2e dependencies into e2e/go.mod

Browse Source 
Several packages are only used while running the e2e suite. These
packages are less important to update, as the they can not influence the
final executable that is part of the Ceph-CSI container-image.

By moving these dependencies out of the main Ceph-CSI go.mod, it is
easier to identify if a reported CVE affects Ceph-CSI, or only the
testing (like most of the Kubernetes CVEs).

Package otlptracegrpc provides an OTLP span exporter using gRPC.
By default the telemetry is sent to https://localhost:4317.
Exporter should be created using [New].
The environment variables described below can be used for configuration.
OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT (default: "https://localhost:4317") -
target to which the exporter sends telemetry.
The target syntax is defined in https://github.com/grpc/grpc/blob/master/doc/naming.md.
The value must contain a host.
The value may additionally a port, a scheme, and a path.
The value accepts "http" and "https" scheme.
The value should not contain a query string or fragment.
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT takes precedence over OTEL_EXPORTER_OTLP_ENDPOINT.
The configuration can be overridden by [WithEndpoint], [WithEndpointURL], [WithInsecure], and [WithGRPCConn] options.
OTEL_EXPORTER_OTLP_INSECURE, OTEL_EXPORTER_OTLP_TRACES_INSECURE (default: "false") -
setting "true" disables client transport security for the exporter's gRPC connection.
You can use this only when an endpoint is provided without the http or https scheme.
OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT setting overrides
the scheme defined via OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT.
OTEL_EXPORTER_OTLP_TRACES_INSECURE takes precedence over OTEL_EXPORTER_OTLP_INSECURE.
The configuration can be overridden by [WithInsecure], [WithGRPCConn] options.
OTEL_EXPORTER_OTLP_HEADERS, OTEL_EXPORTER_OTLP_TRACES_HEADERS (default: none) -
key-value pairs used as gRPC metadata associated with gRPC requests.
The value is expected to be represented in a format matching the [W3C Baggage HTTP Header Content Format],
except that additional semi-colon delimited metadata is not supported.
Example value: "key1=value1,key2=value2".
OTEL_EXPORTER_OTLP_TRACES_HEADERS takes precedence over OTEL_EXPORTER_OTLP_HEADERS.
The configuration can be overridden by [WithHeaders] option.
OTEL_EXPORTER_OTLP_TIMEOUT, OTEL_EXPORTER_OTLP_TRACES_TIMEOUT (default: "10000") -
maximum time in milliseconds the OTLP exporter waits for each batch export.
OTEL_EXPORTER_OTLP_TRACES_TIMEOUT takes precedence over OTEL_EXPORTER_OTLP_TIMEOUT.
The configuration can be overridden by [WithTimeout] option.
OTEL_EXPORTER_OTLP_COMPRESSION, OTEL_EXPORTER_OTLP_TRACES_COMPRESSION (default: none) -
the gRPC compressor the exporter uses.
Supported value: "gzip".
OTEL_EXPORTER_OTLP_TRACES_COMPRESSION takes precedence over OTEL_EXPORTER_OTLP_COMPRESSION.
The configuration can be overridden by [WithCompressor], [WithGRPCConn] options.
OTEL_EXPORTER_OTLP_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE (default: none) -
the filepath to the trusted certificate to use when verifying a server's TLS credentials.
OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CERTIFICATE.
The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE (default: none) -
the filepath to the client certificate/chain trust for client's private key to use in mTLS communication in PEM format.
OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE.
The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
OTEL_EXPORTER_OTLP_CLIENT_KEY, OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY (default: none) -
the filepath to the client's private key to use in mTLS communication in PEM format.
OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY takes precedence over OTEL_EXPORTER_OTLP_CLIENT_KEY.
The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] option.

# Experimental Features
The SDK contains features that have not yet stabilized in the OpenTelemetry specification.
These features are added to the OpenTelemetry Go SDK prior to stabilization in the specification so that users can start experimenting with them and provide feedback.
These feature may change in backwards incompatible ways as feedback is applied.
See the [Compatibility and Stability](#compatibility-and-stability) section for more information.
## Features
- [Resource](#resource)
### Resource
[OpenTelemetry resource semantic conventions] include many attribute definitions that are defined as experimental.
To have experimental semantic conventions be added by [resource detectors] set the `OTEL_GO_X_RESOURCE` environment variable.
The value set must be the case-insensitive string of `"true"` to enable the feature.
All other values are ignored.
<!-- TODO: document what attributes are added by which detector -->
[OpenTelemetry resource semantic conventions]: https://opentelemetry.io/docs/specs/semconv/resource/
[resource detectors]: https://pkg.go.dev/go.opentelemetry.io/otel/sdk/resource#Detector
#### Examples
Enable experimental resource semantic conventions.
```console
export OTEL_GO_X_RESOURCE=true
```
Disable experimental resource semantic conventions.
```console
unset OTEL_GO_X_RESOURCE
```
## Compatibility and Stability
Experimental features do not fall within the scope of the OpenTelemetry Go versioning and stability [policy](../../../VERSIONING.md).
These features may be removed or modified in successive version releases, including patch versions.
When an experimental feature is promoted to a stable feature, a migration path will be included in the changelog entry of the release.
There is no guarantee that any environment variable feature flags that enabled the experimental feature will be supported by the stable version.
If they are supported, they may be accompanied with a deprecation notice stating a timeline for the removal of that support.
