Configurable storage engine for Netdata agents: step 1 (#12776)
* rrd: move API structures out of rrddim_volatile
In C, unlike C++, it's not possible to reference a nested structure
from outside this structure.
Since we later want to use rrddim_query_ops and rrddim_collect_ops
separately from rrddim_volatile, move these nested structures out.
* rrd: use opaque handle types for different memory modes
