Fixes#1498
When shutting down the application, it was possible to
reference stale ocf_cache pointer. This was the case
when two or more vbdev_ocf devices were based on top
of single cache bdev.
This issue did not occur outside of the shutdown case,
since RPC only allows deletion of the vbdev_ocf.
This erases on disk metadata and next run of the application,
would not detect such vbdev_ocf.
Shutdown meanwhile works different, by first stopping
the instance of running "ocf_mngt_cache" and later detaching
"core" devices (the ones being cached). This prevented
erasing the on disk metadata and allowed for restarted
application to detect vbdev_ocf.
See patch (1292ef2) for details.
Since references to ocf_cache are copied between vbdev_ocf
[see start_cache()], the reference count inside ocf_cache
was limited to original ocf_mngt_cache_start() and
management queue creation. First call into ocf_mngt_cache_stop()
released all references to ocf_cache. Leaving other
vbdev_ocfs pointing to released memory.
This patch works around this issue by increasing ref cnt
on ocf_cache for each vbdev based on top of it.
It allows to call into ocf_mngt_cache_stop(), but not
release the memory for ocf_cache until last vbdev.
Note:
A proper redesign here is in order:
- either rearranging structures to be based around single ocf_cache,
rather than multiple vbdev_ocf instances
- better use of OCF API to reduce book keeping logic in vbdev
There are plans to implement detach/attach in RPC,
so it should be a focus during that effort.

This will allow us to use timing_enter and timing_exit directly
inside the run_test function. That function already lends itself well to
nesting the way we do our timing.
This patch series is aimed at combining the timing_*, run_test, and
report_test_completions calls all into a single place. This will greatly
reduce the number of lines of code in our bash scripts devoted to
tracking timing, formatting, and test completion. It will also enable us
to expand on the reporting of test completions. Further down the line,
this will also allow us to unify test case documentation.

were not related to ocf bdev IO handling (issue #1025).
This patch isolates the RPC call to separate test.

This patch is related to issue #815. To avoid hung and re-enable
testing this part of ocf, this patch changes backed device from aio to
nvme.
Hung in this test was caused by implementation of AIO bdev and bdev layer.
All AIO bdevs are using the same shared context with limited queue depth,
so in some cases AIO can return NOMEM status. It's ok when we have more
than one IO from bdev layer perspective, if not we will stuck because
nothing will triger retry io procedure.
This patch only enables testing and are not fixing root cause of hung.
To prevent before unexpected behavior of this and next one test we
need to clear ocf metadata on nvme device.
This patch also reenables this test in CI.
