This runs cram tests, which are an easy way to test output
stays consistent. We already use cram for basic cli tests with no cluster,
and now we can use it for whole system tests too.
ceph.git master now separates across crush hosts without this setting.
For teuthology clusters, we don't want that (unless the tests specifies
otherwise).
This patch adds the ability to barrier between
parallel exec tasks so that all tasks will perform
the following step (after the barrier) at the same
time.

We don't want to do an exec per role, but per-host. We
were already doing an exec per host, but the names were confusing.
This fixes the names up and removes the role parameters.

Will run for as long as teuthology runs. By default, fails if any clock
skews higher than 0.05 seconds are detected, but will only fail when the
teuthology run finishes and after reporting a list of all the detected
skews.
Accepted options:
interval amount of seconds to wait in-between checks. (default: 30.0)
max-skew maximum skew, in seconds, that is considered tolerable
before issuing a warning. (default: 0.05)
expect-skew 'true' or 'false', to indicate whether to expect a skew
during the run or not. If 'true', the test will fail if no
skew is found, and succeed if a skew is indeed found; if
'false', it's the other way around. (default: false)
never-fail Don't fail the run if a skew is detected and we weren't
expecting it, or if no skew is detected and we were
expecting it. (default: False)

This new config option obviously defaults to 'true' in order to not only
maintain compatibility, but because it makes sense.

This task configures and starts a Hadoop cluster.
It does not run any jobs, that must be done after
this task runs.
Can run on either Ceph or HDFS.

This generates a new keypair, pushes it to all nodes
in the context and adds all hosts to all other hosts
.ssh/authorized_keys file.
Cleans up all keys and authorized_keys entries
afterwards.

xfstests itself still seems to have some global dependencies that
make it hard to run more than one instance per node, so keep
the one client per node restriction.
Name the image after the client using it, and only run the
nested context managers once, so this task can work with
more than one client.

Tests scenario where merge_old_entry encounters a divergent
entry where the prior_version is prior to log_tail. This
is a problem since it will go into the missing set, but won't
be re-added to the missing set during read_log() if the node
restarts prior to recovering the object.
