[CHIA-504] Add support for external signers (PLEASE SQUASH)

[Quexington]

This is a "catchup" from long_lived/vault containing all of the features necesary to support external signers according to CHIPs 27-31. The RPC support was already in place, but this pipes that functionality through to the command line and allows the wallet to act as a signer for transactions generated by other, potentially observer wallets.

It's important to squash this PR because I made a series of [UNDO] commits on top of the history of long_lived/vault in order to separate out the changes I didn't want. In this way the long_lived process hopefully has more weight than when I squashed a bit of it preemptively in an earlier "catchup". If this PR is not squashed when it's merged, then the next catchup to the vault branch will essentially eliminate its diff because there are later changes that undo stuff that has already been done.
