Resolves#206. There some minor fixes left to do, but they demand improvements in helio:
1. Remove spurious socket configuration calls that fail on uds.
2. Remove incorrect port printing for uds listener (listener_interface.cc:79).

This statistic helps understanding how much Dragonfly memory grows via updating the existing value vs the new ones.

1. No entries data is written into a journal yet.
2. Introduced a state machine to start and stop journal using a new auxillary command "dfly".
3. string_family currently calls an universal command Journal::RecordEntry that should
save the current key/value of that entry. Please note that we won't use it for all the operations
because for some it's more efficient to record the action itself than the final value.
4. no locking information is recorded yet so atomicity of multi-key operations is not preserved for now.

Docker release pipeline can not push to protected main branch using
the service token. This switches to PAT secret.

Related to #159. Before this change, rdb loading thread has been creating all the redis objects as well.
Now we separate rdb file parsing and objects creation. File parsing phase produces a load trace of one or more binary blobs.
Those blobs are then passed to the threads that are responsible to manage the objects.
The second phase is object creation based on the trace that was passed. Finally those binary blobs are destroyed.
As a result, each thread creates objects using the memory allocator it owns and memory stats become consistent.

1. Fix SendStringArr logic. Consolidate both string_view and string variants to using the same code.
2. Tighten the test framework so that it will test that the parser consumed the whole response.

1. Make it use vectorized send instead of concatenating everything into a single string.
2. vectorized SendStringArr could fail sending large arrays for lengths higher than 512 (returned EMSGSIZE).
We improved the implementation so it would send those arrays in chunks of 256 items.

In rare cases a scheduled transaction is not scheduled correctly and we need
to remove it from the tx-queue in order to re-schedule. When we pull it from tx-queue
and it has been located at the head, we must poll-execute the next txs in the queue.
1. Fix the bug.
2. Improve verbosity loggings to make it easier to follow up on tx flow in release mode.
3. Introduce /txz handler that shows currently pending transactions in the queue.
4. Fix a typo in xdel() function.
5. Add a py-script that reproduces the bug.

The old code relied on c strtod function that expected some sort of delimiter
at the end. Coincidently my unit-testing code always passed proper c strings so
strod worked as expected. EVAL passes slices to non-c string and this is why the bug was
discovered via eval call. Fixes#148.
