Add remaining resources to profile configs

[dsgouda]

There are a few resources for which we need to create profile tags in the spec repo

Resouce	Spec path	2018-03-01-hybrid spec version	2017-03-09-profile spec version
dnsZones	dns/resourcemanager	2016-04-01	2016-04-01
locks	resources/resourcemanager	2016-09-01	2015-01-01
policyAssignments	resources/resourcemanager	2016-12-01	2015-10-01-preview
policyDefinitions	resources/resourcemanager	2016-12-01	2015-10-01-preview

Once this is done, we need to regenerate the code for multi profile SDKs (also involves fixing code generation scripts)
