[Don't Merge] Transfer profile and their connections from one wallet to another.

[abishekk92]

We already had the ability to transfer profile from one wallet to another. However, our existing schema doesn't render the connections protable. Perhaps, time we made it portable.

Here is how we are going to do it.

1. Create CBox
2. Create a connection and set authority to CBox. (authority can no longer be a signer, upon
   closing a connection the rent deposit should go back to the owner of the cbox)
3. For existing connections, migrate connection from user authority to connection box
4. Whenever a user wants to migrate their profile next, they should be able to do so by
   changing the authority of the profile and then of the connection box.
5. Existing users should intialize a connection box.
6. Move their existing connections in the following way.
   1. Initialize a connection box if it doesn't exist.
   2. Close the current connection account
   3. Create a new connection account with the right connection box.
   4. Preferably do all of this in a single ix so that multiple connections can be batched in
      a tx.
