tests: add require_jewel_osds before upgrading last hammer node

Note: this commit was inspired by
http://github.com/ceph/ceph-qa-suite/commit/50758a4810794d265c5d36a71d1e16799251a00d

As of 10.2.4, when upgrading a cluster from hammer to jewel, after the last
node is upgraded the MON will put the cluster into HEALTH_WARN and say: "all
OSDs are running jewel or later but the 'require_jewel_osds' osdmap flag is not
set". The release notes say:

    This is a signal for the admin to do "ceph osd set require_jewel_osds" – by
    doing this, the upgrade path is complete and no more pre-Jewel OSDs may be
    added to the cluster.

qa/tasks/workunit: clear clone dir before retrying checkout

If we checkout ceph-ci.git, and don't find a branch,
we'll try again from ceph.git. But the checkout will
already exist and the clone will fail, so we'll still
fail to find the branch.

The same can happen if a previous workunit task already
checked out the repo.

Fix by removing the repo before checkout (the first and
second times).  Note that this may break if there are
multiple workunit tasks running in parallel on the same
role.  That is already racy, so if it's happening, we'll
want to switch to using a truly unique clonedir for each

client: don't use special faked-up inode for /..

The CEPH_INO_DOTDOT thing is quite strange. Under most OS (Linux
included), the parent of the root is itself. IOW, at the root, '.' and
'..' refer to the same inode.

Change the ceph client to do the same, as this allows users to get
valid stat info for '..', as well as elimnating some special-casing.

Also in several places, we're checking dn_set.empty as an indicator
of being the root. While that is true for the root, it's also true
for unlinked directories.

This patch has treats them the same. An unlinked directory will
be reparented to itself, effectively acting as a root of its own.

qa/tasks/workunit: clear clone dir before retrying checkout

If we checkout ceph-ci.git, and don't find a branch,
we'll try again from ceph.git. But the checkout will
already exist and the clone will fail, so we'll still
fail to find the branch.

The same can happen if a previous workunit task already
checked out the repo.

Fix by removing the repo before checkout (the first and
second times).  Note that this may break if there are
multiple workunit tasks running in parallel on the same
role.  That is already racy, so if it's happening, we'll
want to switch to using a truly unique clonedir for each
instantiation.

Convert to using "tar-pax" which should make it use the posix format.
Any build machine that we're reasonably targeting should support it.
