Ramana Raja 2f2cd3bcff qa/suites/rbd: add test to check rbd_support module recovery
... on repeated blocklisting of its client.

There were issues with rbd_support module not being able to recover
from its RADOS client being repeatedly blocklisted. This occured for
example in clusters with OSDs slow to process RBD requests while the
module's mirror_snapshot_scheduler was taking mirror snapshots by
requesting exclusive locks on the RBD images and workloads were running
on the snapshotted images via kernel clients.

-------------

clusters/    - some predefined cluster layouts
suites/      - set suite

The suites directory has a hierarchical collection of tests.  This can be
freeform, but generally follows the convention of

  suites/<test suite name>/<test group>/...

A test is described by a yaml fragment.

A test can exist as a single .yaml file in the directory tree.  For example:

 suites/foo/one.yaml
 suites/foo/two.yaml

is a simple group of two tests.

A directory with a magic '+' file represents a test that combines all
other items in the directory into a single yaml fragment.  For example:

 suites/foo/bar/+
 suites/foo/bar/a.yaml
 suites/foo/bar/b.yaml
 suites/foo/bar/c.yaml

is a single test consisting of a + b + c.

A directory with a magic '%' file represents a test matrix formed from
all other items in the directory.  For example,

 suites/baz/%
 suites/baz/a.yaml
 suites/baz/b/b1.yaml
 suites/baz/b/b2.yaml
 suites/baz/c.yaml
 suites/baz/d/d1.yaml
 suites/baz/d/d2.yaml

is a 4-dimensional test matrix.  Two dimensions (a, c) are trivial (1
item), so this is really 2x2 = 4 tests, which are

  a + b1 + c + d1
  a + b1 + c + d2
  a + b2 + c + d1
  a + b2 + c + d2

A directory with a magic '$' file, or a directory whose name ends with '$',
represents a test where one of the non-magic items is chosen randomly.  For
example, both

 suites/foo/$
 suites/foo/a.yaml
 suites/foo/b.yaml
 suites/foo/c.yaml

and

 suites/foo$/a.yaml
 suites/foo$/b.yaml
 suites/foo$/c.yaml

is a single test, either a, b or c.  This can be used in conjunction with the
'%' file in the same (see below) or other directories to run a series of tests
without causing an unwanted increase in the total number of jobs run.

Symlinks are okay.

One particular use of symlinks is to combine '%' and the latter form of '$'
feature.  Consider supported_distros directory containing fragments that define
os_type and os_version:

 supported_distros/%
 supported_distros/centos.yaml
 supported_distros/rhel.yaml
 supported_distros/ubuntu.yaml

A test that links supported_distros as distros (a name that doesn't end with
'$') will be run three times: on centos, rhel and ubuntu.  A test that links
supported_distros as distros$ will be run just once: either on centos, rhel or
ubuntu, chosen randomly.
