Allow to filter a list by role
Currently, content to deploy to /var/wwwroot are split
in mastodon, shellserver and webserver-legacy roles.
Plan is to consolidate all of them in the webserver-content
role, and from webserver-content/init.sls, to include the relevant
states files according the target role.
To use node.has_role with if condition isn't pretty, especially as
a sls file can't only have one unique include entry.
Instead, this change provides a node.filter_by_role method, to be
able to create a pillar like this:
web_content_sls: mastodon: - .org/nasqueron/social shellserver: - .com/paysannerebelle - .org/eglide webserver-legacy: - .be/dereckson - .org/nasqueron/docs
Then, node.filter_by_role('web_content_sls') called on a node
with the mastodon role will return this list:
Test Plan: Unit tests have been provided for the new method.
