Use of (p)redis transactions prevents use of sentinel for high-availability redis deployment

[pdbreen]

Attempting to deploy Horizon using redis-sentinel (via https://github.com/monospice/laravel-redis-sentinel-drivers) for high-availability is mostly working. However, it hits the following exception when attempting to gather stats (and possibly other operations).

Predis\NotSupportedException · Cannot initialize a MULTI/EXEC transaction over aggregate connections.
Raw

The following - predis/predis#404 - indicates this can be avoided

That said, it's still possible to avoid $client->transaction(), which uses the above-mentioned abstraction, and just use the good old MULTI and EXEC commands (that is, $client->multi() and $client->exec()).

Any chance of Horizon being updated to make use of this work around?

Submitted PR to https://github.com/monospice/laravel-redis-sentinel-drivers that will resolve.
