Pass the user specified token to consul maintenance primitive

Otherwise we use the "globally configured" token, that may change at
any point in the chef run (because of diplomat model).
Let's specify the token when requested. i.e. all checks calls.

If an incorrect token is used, it may lacks permission to detect the
node/service maintenance.
