grafana plugin install/check breaks catalog run when grafana-server service is not running

[jfschneider]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 4.10.6 aio
• Ruby: 2.1.9p490
• Distribution: RHEL7
• Module version: 4.0.2
• grafana: grafana-4.5.1-1.x86_64

How to reproduce (e.g Puppet code you use)

include ::grafana

grafana::plugins:
  'grafana-simple-json-datasource':
    ensure: 'present'

What are you seeing

Error: Failed to apply catalog: Execution of '/usr/sbin/grafana-cli plugins ls' returned 1: Error: ✗ error: stat /var/lib/grafana/plugins: no such file or directory

NAME:
   Grafana cli plugins ls - list all installed plugins

USAGE:
   Grafana cli plugins ls [arguments...]

What behaviour did you expect instead

at least this error should not stop the catalog apply

Output log

see above

Any additional information you'd like to impart

The problem seems that /var/lib/grafana/plugins is created at first startup of grafana-server, beforehand it does not exist. So there is a dependency
Class['grafana::service'] -> Grafana_Plugin <| |>
but that is not possible because of
Grafana_Plugin <| |> ~> Class['grafana::service']
in init.pp

Issue occurs when provisioning a new server, setting dependency results in dependency cycle error.
