dc9c076ef3 Remove space from names of internal volumes 
Those names are used for creating allocators. In Linux kernel environment
starting from version 5.12 there is a kernel warning if allocator name
contains spaces. This patch resolves this problem by replacing spaces with
underscores.

c677f65212 Avoid double initialization of cleaning policy in standby mode 
Cleaning policy is initialized on standby activate, after all the metadata
from primary cache is flushed and the actual recovery is being performed.
Thus initializing it earlier on standby attach is incorrect.

Fix core load cleanup loop

77380d6579 Fix core load cleanup loop 
conf_meta->core_count is not modified during load/recovery in the latest
version. Thus in case of error in cores initialization, in order to
iterate over the initialized cores we must depend on core->added only,
regardles of conf_meta->core_count value. for_each_core() macro does
exactly this.

9c751dd2b8 Manage valid_core_bitmap properly 
Set bit only on core addition and clean it on core removal.

This allows to avoid conf metadata modification in load / standby load
paths, which effectively prevents issues with metadata mismatch during
consequent standby activate attempts after initial activate failure.
Previously the first attempt changed the metadata, so on comparison with
metadata on drive failed on any following attempt, leading to inability
to activate the cache.
