[client] Allow unlimited unlock attempts

The ask-for-password command has an option
to specify the maximum number of retries to
get the correct password.  The default number
of retries was 3.  This makes sense for /opt,
and to a lesser degree /home, but it doesn't
make sense at all for /, since failing means
the system won't boot.

The new default is "unlimited".  This fixes the
/ case, but has the downside that all integration
code that was depending on the 3 default before
will need to get updated.
