Subject: [PATCH] feat(matrix): Define SLO for matrix-synapse
This patch implements a first SLO using sloth for the matrix-synapse
deployment. First tests with sloth for SLO overview.
While this should be neccesary, but it could be useful to build some
nice dashboards and compare to other solutions.
