For Ansible 2.10 compat, change imports to use module_utils already in this collection

[AlanCoding]

SUMMARY

This collection will not work with Ansible 2.10 because that will no longer host the old module_utils specific to content like this.

I verified that imports fail with ansible==2.10.0a1.

This solution, using relative imports, will sacrifice compatibility with Ansible 2.8, and I am updating metadata to reflect that. It is still possible to make this work with both 2.8 and 2.10 if you type out the fully qualified collection name for each import, which is like

azure/plugins/modules/azure_rm_resourcegroup.py

Line 132 in 8aad2a0

from ansible_collections.azure.azcollection.plugins.module_utils.azure_rm_common import AzureRMModuleBase, normalize_location_name

As you can see from this link, some modules already use these fully-qualified style imports. I'm not changing those here.

Why are some modules using fully-qualified imports and others not? I see the one I linked in #45, which states that it is the 4th migration of modules... and I can find #52 migrated a much larger number without using the fully-qualified imports.

ADDITIONAL INFORMATION

The module utils were already here:

I previously put up #115, and this is very similar, although it's not moving anything, just redirecting stuff.

I think @Fred-sun addressed all these in #140
