cli: unify RPC endpoint flags under options package

Browse source 
This makes rpc flags consistent across all commands, previously some commands
used 'endpoint, e' and some 'rpc, r', some had ability to change timeout and
some hadn't. Now 'rpc-endpoint, r' is used everywhere along with 'timeout, t'.
