mgr/dashboard: Push Grafana dashboards on startup

Because we didn't have viable way to populate Grafana dashboards in a
fully containerized context, we needed a different method. This will
work in packaged and containerized deployments.

We provide three methods to push the dashboard JSON files to the Grafana
instance: a command (ceph dashboard update-grafana-dashboards); an API
endpoint (/api/grafana/update_dashboards); and an automatic on-startup
feature that is disabled by default (ceph dashboard
set-grafana-update-dashboards true). The on-startup method will also
retry periodically to avoid racing with the startup of Grafana itself.

client: clean up error checking and return of _lookup_parent

ll_lookup_inode can end up getting back 0 from _lookup_parent,
without zeroing out the parent pointer, which ends up remaining
uninitialized.

Fix this by moving most of the sanity checks in _lookup_parent
into ll_lookup_inode, and only have it issue the call to the MDS.

This also allows us to do the checks in a more sane order.

common/secret.c: fix key parsing when doing a remount

When doing a CephFS remount (-o remount) the secret is parsed from procfs
and we get '<hidden>' as a result and the mount will fail with:

  secret is not valid base64: Invalid argument.
  adding ceph secret key to kernel failed: Invalid argument.

As the kernel already have the key, we simply need to use it.
