[Feature] Replication Profile

[jcace]

Replication Profiles will allow users to configure many parameters for replicating content to providers.

This will enable control of the following on a per-dataset-per-SP basis:

• Unsealed copy
• Announce to indexer

For example,

• Dataset A can be replicated to SPA and SPB, where SPA will keep an unsealed copy and announce to indexer while SPB will not keep an unsealed copy, but will still announce to indexer

[jcace]

We will accomplish this by modifying the ProviderAllowedDatasets model and changing it to ReplicationProfile, and moving the unsealed copy and announce to indexer flags here.

This table will maintain the many-many relationship between Datasets and Providers, and will facilitate additional configuration regarding what's allowed to be replicated.

[jcace]

A new endpoint /replication_profiles will be added with GET, POST, DELETE, and PUT routes for modifying this table. It will be decoupled from the /providers endpoint as it will take on additional complexity when we build out more features on it.
