There are some usage peak from time to time where we exceed the current number
of requests our current replicas can handle. This is to reduce 502 errors.

It was misindented from 2 characters.

Otherwise, we schedule and fill-in queues which are not consumed. This then
escalates to spurious infra alerts.

Those loaders were stopped to avoid running too much loaders in the staging infra.

It's mostly the same way to trigger it. Only some configuration manipulation
must slightly be adapted to allow the extra service to deploy it.

The scheduler-runner already allows it but it was used only in the
`start-runner --with-priority` call. Now, we'll be able to run if for both.

This is just the list of task types so name it properly.

The kubernetes scheduler should do the right thing.

That pvc/pv will be accessible from 2 pods objstorage-{ro,rw} on the same
host.

Avoid using ceph storage. It should be used for programs that does a moderate
amount of I/O but still needs "singleton" persistence.

Objstorage can be I/O intensive.

PV does not declare namespace.

Add one objstorage-pathslicing-pvc to manage the next-version objstorage.
That way, the data stored won't get decommissionned when the argocd
next-version is stopped.

This allows to share the pv/pvcs declaration instead of duplicating it inside
the various templates using it (e.g. graph, alter, cassandra-checks, ...)

The svn request are usually taking time to be processed.

A few number of scn or mercurial requests can delay the processing
of a majority of git repositories
