DevStack plugin to configure Ceph backend.

Goutham Pacha Ravi ad7e234ff6 [manila] Fix pre-test-hook to not setup ipv6 always IPv6 export policy support was added to the Manila CephFS-via-NFS driver in the Train release. This devstack plugin is branchless, so we'll need to check for the relevant branch to setup the ipv6 test harness. The pre-test and post-test hooks will be deleted soon when devstack-gate is dropped by manila test jobs in the Victoria cycle. So this code is temporary but required to make ceph-via-nfs tests pass in stable/queens-stein branches.

Devstack Ceph Plugin

Devstack plugin to configure Ceph as the storage backend for openstack services

As part of stack.sh:

Installs Ceph (client and server) packages
Creates a Ceph cluster for use with openstack services
Configures Ceph as the storage backend for Cinder, Cinder Backup, Nova, Manila (not by default), and Glance services
(Optionally) Sets up & configures Rados gateway (aka rgw or radosgw) as a Swift endpoint with Keystone integration
- Set ENABLE_CEPH_RGW=True in your localrc
Supports Ceph cluster running local or remote to openstack services

As part of unstack.sh | clean.sh:

This plugin also gets used to configure Ceph as the storage backend for the upstream Ceph CI job named gate-tempest-dsvm-full-devstack-plugin-ceph

To get started quickly, just enable the plugin in your local.conf:

enable_plugin devstack-plugin-ceph https://opendev.org/openstack/devstack-plugin-ceph

Run stack.sh in your devstack tree and boom! You're good to go.
Ceph is setup as the default storage backend for Cinder, Cinder Backup, Glance and Nova services. You have the ability to control each of the enabled services with the following configuration in your local.conf:
```
ENABLE_CEPH_CINDER=True     # ceph backend for cinder
ENABLE_CEPH_GLANCE=True     # store images in ceph
ENABLE_CEPH_C_BAK=True      # backup volumes to ceph
ENABLE_CEPH_NOVA=True       # allow nova to use ceph resources
```
Change any of the above lines to False to disable that feature specifically.
Ceph can be enabled as the storage backend for Manila with the following setting in your local.conf:
```
ENABLE_CEPH_MANILA=True
```
CephFS Native driver that supports native Ceph protocol is used by default. To use CephFS NFS-Ganesha driver that supports NFS protocol add the setting:
```
MANILA_CEPH_DRIVER=cephfsnfs
```
Make sure that the manila plugin is enabled before devstack-plugin-ceph in the local.conf file.
Then run stack.sh and wait for the magic to happen :)

Rados Gateway with Keystone for Swift - works on Ubuntu only
Tempest test failures when using RGW as swift endpoint
Tempest fails due to verify-tempest-config erroring out, when using RGW as swift endpoint
- Patch sent @ https://review.openstack.org/#/c/264179/
Manila with CephFS - for Ubuntu, support only for Trusty Tahr (14.04 LTS) and beyond
