Failed to deploy the LMA collector with remote backends

[Simon Pasquier]

Environmnet:

MOS 9 with LMA master.

Steps to reproduce:

1. Create an environment with 1 controller (node-1) & 1 compute (node-2)
3. install the LMA collector plugin.
4. Enable and configure the plugin to use remote Elasticsearch and InfluxDB (use fake addresses).
6. Deploy the environment and wait for completion.

Expected result:

The environment is ready.

Actual result:

The deployment fails with an error:

Tasks 'elasticsearch-kibana-configuration, influxdb-configuration' can't be in requires|required_for|groups|tasks for [lma-backends] because they don't exist in the graph

Workaround:

Install and enable the ES and InfluxDB plugins in the environment without assigning any role.

According to a previous discussion [1] with the Fuel team, this shouldn't happen so the bug may be reassigned to Fuel.

    Fix tasks dependency when using remote backends

    Previously the LMA collector had an explicit dependency on the last
    Elasticsearch task but this doesn't work when the Elasticsearch/Kibana
    plugin isn't deployed in the same environment as the collector plugin.

    This change makes sure that the LMA collector plugin's tasks will only
    be executed once the Elasticsearch cluster is fully functional by
    pinning both plugins to a well-known task (update_hosts in that case).
