Vladimir Kozhukalov 978507351f Add ceph-adapter-rook chart
When using Rook for managing Ceph clusters we have
to provision a minimal set of assets (keys, endpoints, etc.)
to make Openstack-Helm charts work with these Ceph clusters.

Rook provides CRDs that can be used for managing Ceph assets
like pools/keyrings/buckets etc. but Openstack-Helm can not
utilize these CRDs. To support these CRDs in OSH would
require having lots of conditionals in OSH templates since
we still want OSH to work with OSH ceph-* charts.

# Summary
This is the minimal set of templates necessary to make the rest
of Openstack-Helm charts work with Ceph clusters managed by the
Rook operator. Rook operator not only deploys Ceph clusters but
also provides convenience when interfacing with those clusters
via CRDs which can be used for managing pools/keys/users etc.
However Openstack-Helm charts do not utilize Rook CRDs but instead
manage Ceph assets like pools/keyrings/users/buckets etc. by means
of running bootstrap scripts. Before using Openstack-Helm charts we
have to provision a minimal set of assets like Ceph admin keys and
endpoints and this chart provides exactly this minimal set of templates.
# Usage
Deploy Ceph admin key and Ceph mon endpoint in the namespace where Ceph cluster is deployed.
```
tee > /tmp/ceph-adapter-rook-ceph.yaml <<EOF
manifests:
configmap_bin: true
configmap_templates: true
configmap_etc: false
job_storage_admin_keys: true
job_namespace_client_key: false
job_namespace_client_ceph_config: false
service_mon_discovery: true
EOF
helm upgrade --install ceph-adapter-rook ./ceph-adapter-rook \
--namespace=ceph \
--values=/tmp/ceph-adapter-ceph.yaml
```
Now wait until all jobs are finished and deploy client key and client
configuration in the namespace where Openstack charts are going to be deployed.
tee > /tmp/ceph-adapter-rook-openstack.yaml <<EOF
manifests:
configmap_bin: true
configmap_templates: false
configmap_etc: true
job_storage_admin_keys: false
job_namespace_client_key: true
job_namespace_client_ceph_config: true
service_mon_discovery: false
EOF
helm upgrade --install ceph-adapter-rook ./ceph-adapter-rook \
--namespace=openstack \
--values=/tmp/ceph-adapter-rook-openstack.yaml
```
Again wait until all jobs are finished and then you can deploy other Openstack-Helm charts.
