qa/cephadm: zap raw devices before OSD deployment
ceph_osds() assumes all teuthology scratch devices are clean
and directly usable by:

 > ceph orch apply osd --all-available-devices --method raw

However, in practice some devices may retain stale BlueStore metadata
(or other data) from previous runs. cephadm correctly skips such
devices, leading to fewer OSDs than expected and causing the test to
timeout waiting for an exact OSD count.

This change adds a pre-deployment cleanup step for `raw-osds` that:
- zaps any existing BlueStore metadata (`ceph-bluestore-tool zap-device`)
- removes filesystem signatures (`wipefs --all`)
- clears initial disk data (`dd`)

This ensures all scratch devices are truly available for OSD
deployment and prevents mismatches between expected and actual OSD
counts.

ceph-qa-suite
-------------

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.

The teuthology code can be found in https://github.com/ceph/teuthology.git

Note: The performance suites clone CBT from master here: https://github.com/ceph/cbt.git
CBT will not support cosbench beyond release tag v0.3, therefore no qa suite should use cosbench.
cosbench support has been removed from qa/tasks/cbt.py.
