cephadm: split cli parsing & ctx setup from logging setup

Split the parsing and processing of the CLI from the logging
setup in the cephadm main func. Move logging setup to occur after
we've determined that there's a runnable command func.

This is preparatory work to allow running `cephadm --help` without being
root.
