* Add the REPOSITORY env to build args to avoid the following error when
executing without the credentials for the repository.
```
ERROR: Service 'compute' failed to build: Head

```
* update the tag version in the documentation to support storage broker
+ neondatabase/cloud#1103
This adds a couple of control endpoints to simplify compute state
discovery for control-plane. For example, now we may figure out
that Postgres wasn't able to start or basebackup failed within
seconds instead of just blindly polling the compute readiness
for a minute or two.
Also we now expose startup metrics (time of the each step: basebackup,
sync safekeepers, config, total). Console grabs them after each
successful start and report as histogram to prometheus and grafana.
OpenAPI spec is added and up-tp date, but is not currently used in the
console yet.
* Rename wal_acceptor binary to safekeeper
* Rename wal_acceptor.pid and wal_acceptor.log to safekeeper.pid and safekeeper.log
* Change some mentions of WAL acceptor to safekeeper
* Dockerfile: alias wal_acceptor to safekeeper temporarily until internal scripts are updated
