This is to avoid copying the many fields of a histogram.Histogram all
the time.
This also fixes a bunch of formerly broken tests.

This can be useful when generating rules, a query may use a duration,
and it may be useful to template that into a URL parameter. Therefore
this allows interfacing with systems that don't implement Prometheus
style duration parsing.

PR #9618 introduced failing to load the config file when agent mode is

* remote-write: slow down retries to avoid DDOS
Increase the default max retry time from 100ms to 5 seconds.
Remote write calls are retried after a recoverable error such as the
back-end returning 500. Prometheus waits the minimum time and retries,
then doubles the wait on each subsequent retry until the maximum is
reached.
If some data is still getting through, remote-write will also increase
shards, and the default maximum is 200. 200 shards sending every 100ms
is 20 calls per second, to a back-end that is already in trouble.
5 seconds was chosen to match the default BatchSendDeadline: if we can
afford to wait that long for no response, then we can wait the same time
to retry. We will reach 5 seconds after 9 successive failures.

It seems sometimes you can get error like:
Error: Not equal:
expected: []byte(nil)
actual : []byte{}
Diff:
--- Expected
+++ Actual
@@ -1,2 +1,3 @@
-([]uint8) <nil>

This commit does what bytes.Equal does to silence those differences. I'm
not sure if this is a correct solution or just covering up the actual bug.

The rules manager keeps a note of which series were generated by the
last run, so it can write a stale marker to those that disappeared.
Since the keys are not for human eyes, we can use a simpler format
and save the effort of quoting label values.
