Follow-up to #884

• the default retry count for outgoing federation is raised by one, so as to tolerate 24h downtime by default
• receiver_worker attempts are spaced out more to better handle resolving objects from temporarily overwhelmed servers (last attempt after about 20min compared to ~1.5 minutes before)

Follow-up to #884 - the default retry count for outgoing federation is raised by one, so as to tolerate 24h downtime by default - receiver_worker attempts are spaced out more to better handle resolving objects from temporarily overwhelmed servers *(last attempt after about 20min compared to ~1.5 minutes before)*

federation/out: raise publisher retries by one ... 50afbc63e4

We now tolerate a whole day of downtime by default
instead of only about three hours.

federation/in: space out receiver retries more ... 258841c310

The most common permanent receiver error arises for likes/boosts
when we don’t yet know the rlevant object and can't fetch it
due to the remote being overwhelmed or otherwise down.

Before this changes all retries were rather rapid
thus not giving the remote enough time to recover
and usually all failing. Now the remote has about 20
minutes to recover before we give up.

Transient errors from race conditions and (presumably)
weird database-cache interactions also occur regularly.
However, they resolve within the first one or two retries
and those intial retries still happen relatively quickly.
