1. QoS provides settings for rbd volume read/write iops
and read/write bandwidth.
2. All QoS parameters are placed in the SC,
send QoS parameters from SC to Cephcsi through PVC create request.
3. We need provide QoS parameters in the SC as below:
- BaseReadIops
- BaseWriteIops
- BaseReadBytesPerSecond
- BaseWriteBytesPerSecond
- ReadIopsPerGB
- WriteIopsPerGB
- ReadBpsPerGB
- WriteBpsPerGB
- BaseVolSizeBytes
There are 4 base qos parameters among them, when users apply for
a volume capacity equal to or less than BaseVolSizebytes, use base
qos limit. For the portion of capacity exceeding BaseVolSizebytes,
QoS will be increased in steps set per GB. If the step size parameter
per GB is not provided, only base QoS limit will be used and not associated
with capacity size.
4. If PVC has resize request, adjust the QoS limit
according to the QoS parameters after resizing.

This commit is the restructure the doc folder to
include sub-folders like csi-addons, rbd, cephfs
to contain related docs and other general docs can be
placed under doc folder.
This will enhance the doc structure will make it easier
for the users to search the docs as it get more populated.

It seems very common in other Go based projects to place the local
packages in the import statement last. Currently Ceph-CSI expects the
imports to group the local packages immediately after standard packages.
This exception compared to other projects often requires new
contributors to 'correct' their PR.
Following a more common convention for grouping imports should make it a
little easier to contribute to the project.

Implemented the capability to include read affinity options
for individual clusters within the ceph-csi-config ConfigMap.
This allows users to configure the crush location for each
cluster separately. The read affinity options specified in
the ConfigMap will supersede those provided via command line arguments.

`/retest all` causes a spike in resource consumption in Jenkins and the
OpenShift cluster kills the Pod. That means tests are not fully running
yet, and results never arrive back in the PR. Instead of `/retest all`,
the `ok-to-test` label can be used to trigger required tests with a
slight delay between each command.

Currently the Ceph-CSI community is on the 'free' Slack instance at
https://cephcsi.slack.com. The Ceph project uses a Slack instance that
we can use for Ceph-CSI as well. In order to integrate more with other
Ceph projects, we should ideally be active on the same Slack instance.
For now, we have `#ceph-csi` as only channel on the
https://ceph-storage-slack.com, we can add more channels if needed.
