Description

Once we have moved arclamp to baremetal (T316223) we'll be in a position to move redis off mwlog and to arclamp hosts. This will help in general to self-contain the service and with T261274: Figure out switchover steps for mwlog hosts. What do (collective) you think ?

Implementation steps:

move arclamp redis config into dedicated profile
add redis to role::webperf::profiling_tools
point mw to arclamp1001 redis in ProductionServices.php
point arclamp to arclamp1001 via profile::webperf::arclamp::redis_host
validate there are no further clients of redis on mwlog
remove redis from mwlog

I'm not seeing any traffic arriving to mwlog1002 on port 6379, considering this confirmation of no further redis clients of mwlog
