OCF relies on our env to get information about free memory.
It then uses that information to return a descriptive
error if not enough memory is available.
But no other calculation done based on that value.
Our implementation was not correct because it returned
the size of available physical memory in the system,
while we use HUGEPAGE memory for most of OCF operations.
There doesn't seem to be a reliant API for getting
the size of available HUGEPAGE memory, so instead
return UINT64_MAX, as it is done in ocf/env/posix/ocf_env.h.
This way, OCF will not know ahead of time if there
is enough memory available, but it will still fail
properly on operations that require too much memory.

New OCF version is ready, so update our submodule.
There were a lot of API changes so
we need to adjust our bdev/ocf and lib/ocf_env code.
Description of code changes:
- env: added small functions like ENV_BUILD_BUG_ON, env_vzalloc_flags
- env: added "destroy" method for all locks
- env: added "execution context" interface
- cache/core "id" field made private
- signature of "ocf_io_configure" changed
- "io->volume" field made private
List of changes to OCF is available at
https://github.com/Open-CAS/ocf/releases
But no new features were implemented for our
OCF module since 19.6

Some of the locks implementation in our OCF env
is different from suggested posix implementation (ocf/env/posix),
which leads to deadlocks in OCF v20.3
This patch copies correct implemention from example
posix env.

This path updates ocf library to version 19.06 and also introduces
all necessary changes required to integrate ocf bdev adapter with
new version of ocf.
Summary of changes introduces with new OCF in ocf bdev:
- ocf_env.h increased limit for memory operations, changed behaviour
of strncpy to less restrictive, both changes are required to run new OCF
- ctx.c changed functions to new from new OCF
- added new cache mode "write only"
- added missed cache modes wa and wi to RPC scripts
- rewritten spdk_rpc_bdev_ocf_get_stats function to use asynhronus
ocf_mngt_cache_read_lock
- used new asynhronus ocf_mngt_cache_flush instead of waiting for request
- removed no longer valid filed - cfg->device.min_free_ram
- changed expected result in metadata_probe_cb

The OCF build was broken by some of the recent changes
to the Makefiles. This change aims to fix that by separating out the ocf
environment from the ocf bdev.
