Support for re-posting content to channel

[tzarebczan]

The Issue

Implement an API where users can re-post a claim to their own channel. Optimally, this would be done via support metadata (to own address). This will require new types/protobufs to be created (lbryio/types#32). Using supports alleviates the need to create a new claim (and claim namespace) to be created.

Considerations:
Reposts would return with channel claims, have a special identifier.
Does it make sense to re-post anonymously?
What fields do we allow to be set with a repost?

I think this issue should be strongly considered as a next feature addition. It would simultaneously be a useful feature AND advance censorship resistance, as we can use the re-posting feature to allow wallet servers to know about which content is reported as a DMCA (or other) violation in a decentralized way.

#2110 is taking the first step toward making reposting happen

Closing this since the basic API is complete.
