Added inspec checks for environment files and specifically prometheus
and node_exporter args. Provided comments throughout the key reference
points for users to signpost the differing approaches to args used along
with more clearly identifying the difference between archive and repo
approach. Tests appear to be working on both approaches though updates
have been focused at repo install method.
Fixes: #59
this commit makes `service name` to consider pillar provided values,
fallback to a consistent `service name` when {archive|package} is available
for the component, or to `service name == name` when no other value
is provided
BREAKING CHANGE: The data dictionary is simplified and expanded.
Retest your states and update pillar data accordingly.
For developer convenience, clientlibs states were introduced.
See pillar.example, defaults.yaml, and docs/README.
