Commit 1c899847 introduced the ability to expose the owner of the instance.
However, this breaks Prometheus if there is no OwnerID in the reservation (Eg. if you are using a private EC2-API introduced by #4333)

* Limit the number of samples remote read can return.

- Return 413 entity too large.
- Limit can be set be a flag.  Allow 0 to mean no limit.
- Include limit in error message.
- Set default limit to 50M (* 16 bytes = 800MB).

* tidy up the discovery logs,updating loops and selects

few objects renamings

removed a very noise debug log on the k8s discovery. It would be usefull
to show some summary rather than every update as this is impossible to
follow.

added most comments as debug logs so each block becomes self
explanatory.

when the discovery receiving channel is full will retry again on the
next cycle.

* discovery: coalesce identical SD configurations

Instead of creating as many SD providers as declared in the
configuration, the discovery manager merges identical configurations
into the same provider and keeps track of the subscribers. When
the manager receives target updates from a SD provider, it will
broadcast the updates to all interested subscribers.

When prom2 came out the storage querier interface consolidated to a
single Select() method. While doing this it makes it impossible as the
implementer of the querier to know if you are being called for metadata
or actual data. The workaround has been to check if the SelectParams are
nil, which the federation call is always nil. This has 2 negative
consequences (1) remote implementations interpret this as a metadata
call, which makes the federation endpoint return nothing. (2) this means
that the storage implementations don't get the same information passed
down to them as far as SelectParams goes.

This diff simply adds SelectParams to the Select() call in the
federation handler

Looking at https://tech.townsourced.com/post/embedding-static-files-in-go/ (which was mentioned in the issue), vfsgen has all the needed features.

In particular:

- Reproducible builds (no issue with timestamping).
- Well maintained and relatively popular.
- Integration with go generate.
- Self-contained (no external dependency).
