Use rooted bank by default in rpc bank selection (#6759)

* Name anonymous parameters for clarity

* Add CommitmentConfig to select bank for rpc

* Add commitment information to jsonrpc docs

* Update send_and_confirm retries as per commitment defaults

* Pass CommitmentConfig into client requests; also various 'use' cleanup

* Use _with_commitment methods to speed local_cluster tests

* Pass CommitmentConfig into Archiver in order to enable quick confirmations in local_cluster tests

* Restore solana ping speed

* Increase wallet-sanity timeout to account for longer confirmation time
