Specifically, provide a total length over all shards of pending txs.
Also, provide number of "free" transactions pending in the queue -
those that could progress immediately but do not because
they are not first in the queue.

fix(zset): Make count optional for zpop{min,max}
The commands should allow count to be optional and
default to 1 as per the official redis command documentation.
Additionally update command flags to write + fast

feat(server): Basic multi transaction modes
This commit adds the notion of multi transaction modes that allow controlling the execution and
locking behaviour of multi transactions.
In general, there are four modes:
- GLOBAL: all commands run within a global transaction. There is no need for recording locks. Lua scripts can theoretically run with undeclared keys.
- LOCK_AHEAD: the transaction locks all keys ahead likewise to a regular transaction and schedules itself.
- LOCK_INCREMENTAL: the transaction determines what shards it has keys in and schedules itself on those shards, but locks only when accessing a new key. This allows other transactions to run ooo alonside with a big multi-transaction that accesses a contended key only at its very end.
- NON_ATOMIC: all commands run separately, no atomicity is provided, likewise to a pipeline
This commit only adds support for the first 3 modes to EXEC commands.

Upon traversing and accessing expirerd elements they will be transparently removed and deleted

chore(server): reduce number of allocations when storing multi-exec commands
This is useful when DF is used to store large blobs and MULTI is used.
Signed-off-by: Roman Gershman <roman@dragonflydb.io>
Introduce a new flag `df_snapshot_format` that controls the default behavior.
The flag itself is defaulted to save snapshots in a new Dragonfly
specific format.
BREAKING CHANGE: before that Dragonfly saved snapshots in rdb format by default.
Now the flag controls which format is chosen when issuing SAVE/BGSAVE commands.
In addition, "SAVE DF", "SAVE RDB" can be used to save using dragonfly/redis formats
accordingly.
