client: Fix leading / issue with mds_check_access

The "Client::mds_check_access" expects the target_path without
leading '/' as it eventually calls the "MDSCapMatch::match_path"
which expects the target_path passed to be with out leading '/'
as well.

The single leading '/' was being removed. But absolute path
constructed did have leading '//', so removing all the leading
'/' was necessary.

This causes the clients not to be able to access a particular
path even though it has a rw permission on the specific path.

The patche fixes the leading '//' issue.

Although main rados nightlies are scheduled to run weekly, they

This commit increases the priority of main rados runs since
these are most important for debugging new failures. To compliment this
increase in priority, this commit also decreases the frequency of squid
rados runs from twice a week to once a week, since once is more than
enough. It also decreases the prioirity of squid runs.
