Remove --claims arg to make-token
Remove --claims arg to make-token

Normally, we would mark a given arg/option as 'deprecated' for
one release before removing it in the next release.  However, the
--claims arg is only used for the 'brkt make-token .... SIGNING-PATH'
form of the make-token command, which is seldom used.  So it should
be OK to remove this arg, as it is now replaced by the --brkt-tag
arg.
