Gears integration (rebased)

[danni-m]

Example of running RedisTimeSeries cluster with 15 main nodes and RedisGears

Note: adjust the module's path given your folder struct.

cd /tests/utils
NODES=15 ADDITIONAL_OPTIONS=" --loadmodule ../../../RedisGears/bin/linux-x64-release/redisgears.so --loadmodule  ../../bin/redistimeseries.so" ./create-cluster start
NODES=15 ./create-cluster create
NODES=15 ./create-cluster call RG.REFRESHCLUSTER

A quick summary on the single shard master vs single shard based on this branch read performance ( using tsbs scale 100 ).
Bellow you can find the overall average latency ( including RTT ) per query type.

queryN	Query type	master (3e45077)	gears_integration_reduce_rebased ( f14409b )	master vs branch
1	single-groupby-1-1-1	3.830	3.130	18%

@danni-m, as measured above the gears_integration_reduce_rebased changes did not affect performance even when not using gears and a single shard.
