Add new module azure_rm_afdruleset to support Azure Frontdoor Standard and Premium

[jartoo]

SUMMARY

This module manages Frontdoor Rulesets for the Standard and Premium services. I propose building this as a separate module in lieu of complicating the azure_cdn_profile module so as to make the management of each of the elements easier. Azure Frontdoor is quite complex, so matching the modules with the Python SDK APIs seems to be the prudent design choice. I opted to include a Rulesets module, even though it appears Rules can create the missing Rulesets, simply for completeness.

Continues to work on #1041 This does not complete this issue, yet.
