Alex Lambert a9680ab17f dashboard: allow disabling of unused features
Unconfigured dashboard features can lead to empty tabs in the dashboard
containing no meaningful content. Allow users to disable dashboard features
they know will not be used.

A list of features to be disabled allows the user to define a streamlined
dashboard as standard across deployments. Defaults to disabling no features,
ensuring that users are sure they do not need the dashboard feature before
disabling it.

Dimitri Savineau 2ee2194ee0 ceph-dashboard: fix oject gateway integration
Since [1] multiple ceph dashboard commands have been removed and this is
breaking the current ceph-ansible dashboard with RGW automation.
This removes the following dashboard rgw commands:

- ceph dashboard set-rgw-api-access-key
- ceph dashboard set-rgw-api-secret-key
- ceph dashboard set-rgw-api-host
- ceph dashboard set-rgw-api-port
- ceph dashboard set-rgw-api-scheme

Which are replaced by `ceph dashboard set-rgw-credentials`

The RGW user creation task is also removed.

Finally moving the delegate_to statement from the rgw tasks at the block
level.

Dimitri Savineau 5e0ace7e54 ceph-dashboard: fix TLS cert openssl generation
With OpenSSL version prior 1.1.1 (like CentOS 7 with 1.0.2k), the -addext

As a solution, this uses the default openssl.cnf configuration file as a
template and add the subjectAltName in the v3_ca section. This temp openssl
configuration file is removed after the TLS certificate creation.
This patch also move the run_once statement at the block level.

Guillaume Abrioux 72a0336c71 dashboard: remove "certificate is valid for" error
When deploying dashboard with ssl certificates generated by
ceph-ansible, we enforce the CN to 'ceph-dashboard' which can makes
application such alertmanager complain like following:

`err="Post https://mgr0:8443/api/prometheus_receiver: x509: certificate is valid for ceph-dashboard, not mgr0" context_err="context deadline exceeded"`

The idea here is to add alternative names matching all mgr/mon instances
in the certificate so this error won't appear in logs.

Dimitri Savineau 0d0f1e71df dashboard: allow remote TLS cert/key copy
When using TLS on the ceph dashboard or grafana services, we can provide
the TLS certificate and key.
Those files should be present on the ansible controller and they will be
copyied to the right node(s).
In some situation, the TLS certificate and key could be already present
on the target node and not on the ansible controller.
For this scenario, we just need to copy the files locally (on each remote
host).

This patch adds the dashboard_tls_external variable (with default to
false) to allow users to achieve this scenario when configuring this
variable to true.

using `timeout -f -s KILL` fixes this issue.

Also, there is no need to use `shell` module here, let's switch to
