6a9dd9828d Move protocol macros into separate header 
Defines.h is a very common header, so lots of modules will be recompiled
on changes.
Move macros for protocol into separate header, this should significantly
decreases number of units to compile on it's changes.

4cecc238d6 Fix SIGSEGV for external GROUP BY and overflow row 
Overflow row is used for GROUP BY if all of the above is true:
- WITH TOTALS is requested
- max_rows_to_group_by > 0
- group_by_overflow_mode = any
- totals_mode != after_having_exclusive

And in case of overflow row and external GROUP BY, once the temporary
file dumps to disk it resets without_key data variant to nullptr, so any
subsequent dump to disk will cause SIGSEGV.

Fix this, by recreating without_key data variant after dumping to disk,
instead of reseting to nullptr.

And also add sanity check (LOGICAL_ERROR) to make error more
deterministic in case of such error.

Found with fuzzer [1].

6a9ec1396a Access aggregate keys by names over indexes 
Relax this to allow accepting aggregate keys in different order (typical
use case is distributed queries, where the initiator server will do
final merge).

c637d99e07 Volumes and storages refactoring: 
1. Moved Volume to separate file
  2. Created IVolume interface and implemented current behaviour in implementation of new interface — VolumeJBOD
  3. Replaced all old volume usages with new VolumeJBOD. Where it is unnecessary to have JBOD — left just IVolume.
  4. Removed old Volume completely
  5. Moved StoragePolicy to separated files
  6. Moved DiskSelector to separated files
  7. Removed DiskSpaceMonitor file

9ca86dbf34 Drop disks reservation in Aggregator 
True reservation (IVolume::reserve()) will not takes compression into
account, and you aggregate a lot of data then it will likely fail even
though it can be completed, but just because you have big
max_bytes_before_external_group_by and huge max_threads it will fail.
