Moving the log functions into its own internal/util/log package makes it
possible to split out the humongous internal/util packages in further
smaller pieces. This reduces the inter-dependencies between utility
functions and components, preventing circular dependencies which are not
allowed in Go.

nlreturn linter requires a new line before return
and branch statements except when the return is alone
inside a statement group (such as an if statement) to
increase code clarity. This commit addresses such issues.

This commit returns actual error returned by the go-ceph API
to the function GetPoolName(..) instead of just returning
ErrPoolNotFound everytime there is error getting the pool id.
There is a issue reported in which the snapshot creation
takes much more time to reach True state
(i.e., between 2-7 mins) and keeps trying to create with
below error though pool is present:
rpc error: code = NotFound desc = pool not found: pool ID (21)
not found in Ceph cluster.
Since we cannot interpret the actual error for the delay in
snapshot creation, it is required to return the actual error
as well so that we can uderstand the reason.

as we have 2 functions for logging. one for logging
with message and another one is for logging with
context. renamed ErrorLog to ErrorLogMsg to log
with messages.

Most consumers of util.ExecCommand() need to convert the returned []byte
format of stdout and/or stderr to string. By having util.ExecCommand()
return strings instead, the code gets a little simpler.
A few commands return JSON that needs to be parsed. These commands will
be replaced by go-ceph implementations later on. For now, convert the
strings back to []byte when needed.

All calls to util.ExecCommand() now pass the context.Context. In some
cases this is not possible or needed, and util.ExecCommand() will not
log the command.
This should make debugging easier when command executions fail.

The sentinel error code had additional fields in the errors, that are
used nowhere. This leads to unneccesarily complicated code. This
change replaces the sentinel errors in utils with standard errors
created with errors.New() and adds a simple JoinErrors() function to
be able to combine sentinel errors from different code tiers.

Several places in the code compared errors directly with the go-ceph
sentinel errors. This change uses the errors.Is() function of go
1.13 instead. The err113 linter reported this issue as:
err113: do not compare errors directly, use errors.Is() instead

gosec-2.3.0 complains about the following:
[/go/src/github.com/ceph/ceph-csi/internal/util/cephcmds.go:146] - G307 (CWE-): Deferring unsafe method "*os.File" on type "Close" (Confidence: HIGH, Severity: MEDIUM)
> defer tmpFile.Close()
By logging the error from Close(), the warning is gone.

InvalidPoolID has recently been added, and can be used in other location
too. As GetPoolID is updated with this patch set, return InvalidPoolID
on errors too.
Signed-off-by: Niels de Vos <ndevos@redhat.com>
GetPoolID() did not return ErrPoolNotFound in case the pool could not be
found. This has been addressed as well, so that looking for an existing
pool behaves the same for checking by Name or ID.

The internal/ directory in Go has a special meaning, and indicates that
those packages are not meant for external consumption. Ceph-CSI does
provide public APIs for other projects to consume. There is no plan to
keep the API of the internally used packages stable.
