config: add --obscure and --no-obscure flags to config create/update

Browse Source 
Before this change there was some ambiguity about whether passwords
were obscured on not passing them into config create or config update.

This change adds the --obscure and --no-obscure flags to make the
intent clear.

It also updates the remote control and the tests.

Fixes #3728

If any of the parameters passed is a password field, then rclone will
automatically obscure them if they aren't already obscured before
putting them in the config file.
**NB** If the password parameter is 22 characters or longer and
consists only of base64 characters then rclone can get confused about
whether the password is already obscured or not and put unobscured
passwords into the config file. If you want to be 100% certain that
the passwords get obscured then use the "--obscure" flag, or if you
are 100% certain you are already passing obscured passwords then use
"--no-obscure". You can also set osbscured passwords using the
"rclone config password" command.
