MINOR: log: support optional 'profile <log_profile_name>' argument to do-log action

MINOR: log: support optional 'profile <log_profile_name>' argument to do-log action

We anticipated that the do-log action should be expanded with optional
arguments at some point. Now that we heard of multiple use-cases
that could be achieved with do-log action, but that are limitated by the
fact that all do-log statements inherit from the implicit log-profile
defined on the logger, we need to provide a way for the user to specify
that custom log-profile that could be used per do-log actions individually

This is what we try to achieve in this commit, by leveraging the
prerequisite work performed by the last 2 commits.
