Policy: Implement breaking change that Resource Mappings must be in a Resource Mapping Group

[jakedoublev]

Background

Resource mapping groups have been implemented to support better organization of resource mappings. To reduce the complexity of the model we are making two breaking changes:

1. Resource mappings are going to be considered adjacent to the policy so that they are never included as part of a namespaced export bundle
2. Resource mappings cannot live without a resource mapping group

Acceptance Criteria

• implement a migration strategy for this
• document the change
• update the protos
• update the CLI

@jakedoublev What is a resource mapping group?

[jakedoublev]

@strantalis Resource Mapping Groups are a concept that allow association of a bunch of resource mappings in a bunch. A tagging vendor could publish a set of resource mappings (as a group) that map their internal software's tags to known policy attributes. See ADR: #1209 and Epic: #1255
