Not every usage of `set_device_path()` needs to print message.
Sometimes it's internal operation and can contain misleading info.

Check if path passed to core adding or cache starting is by-id link
otherwise do not allow to use it except it is exported object's path.
Do not resolve device's by-id path during core addition or cache starting.

This fixes startup bug when core was added to core pool by md-name*
symlink, but cache metadata contained md-uuid* path, which led to
incomplete configuration

Since there is no kernel-kernel api available to communicate
with nvme driver it is more convenient to use some nvme-dedicated
software (e.g. nvme-cli) to manage nvme devices.
It is even not possible to format nvme device with CAS using current
implementation on newest kernels.

Write-only (WO) cache mode is similar to Write-back (WB), however
read operations do not promote data to cache. Reads are mostly
serviced by the core device, only dirty sectors are fetched from
the cache.
Write-only cache mode is behaving similarly to Write-back with
respect to flushing dirty data. For example it is required to
explicitly enable/disable flushing when changing cache mode
from WO to something other than WB.
