Rather than keeping the entire symbol table in memory, keep every nth
offset and walk from there to the entry we need. This ends up slightly
slower, ~360ms per 1M series returned from PostingsForMatchers which is
not much considering the rest of the CPU such a query would go on to
use.
Make LabelValues use the postings tables, rather than having
to do symbol lookups. Use yoloString, as PostingsForMatchers
doesn't need the strings to stick around and adjust the API
call to keep the Querier open until it's all marshalled.
Remove allocatedSymbols memory optimisation, we no longer keep all the
symbol strings in heap memory. Remove LabelValuesFor and LabelIndices,
they're dead code. Ensure we've still tests for label indices,
and add missing test that we can work with old V1 Format index files.
PostingForMatchers performance is slightly better, with a big drop in
allocation counts due to using yoloString for LabelValues:

This adds a new endpoint that provides per metric metadata via the V1 API.
It collapses metadata that is equal across all targets, and aggregates under the same metric name the ones that differ.
* Allow tests to be asserted on response length
Some tests e.g. limit on API responses, don't require an assertion on
equality.
This allows us to assert against response length instead of
equality.

This commit introduces several test cases for the current /targets/metadata API endpoint.
To achieve so, we use a mock of the metadataStore and inject it to the targets under test.
Currently, three success cases are covered: with a metric name, with a target matcher, and with both. As for the failure scenario, the one where we couldn't match against a particular metric is covered.

Previously, the struct `testTargetRetriever` had hardcoded active and dropped targets. This made it difficult to change the target information depending on the test case.
This change introduces a way to define them as arguments and pass it to a constructor for building. It lays a foundation for dynamically defining targets with various set of arguments to test different scenarios.

* React UI: Support custom path prefixes
The challenge was that the path prefix can be set dynamically as a flag
on Prometheus, but the React app bundle is statically compiled in to
expect a given path prefix. By adding a placeholder value to the React
app's index.html and replacing it in Prometheus with the right path
prefix during serving, this injects Prometheus's path prefix into the
React app via a global const.
Threading the path prefix into the different React components could have
been done with React's Contexts (https://reactjs.org/docs/context.html),
but I found the consumer side of context values to be a bit cumbersome
(wrapping entire components in context consumers), so I ended up
preferring direct threading of the path prefix values to components that
needed them. Also, using contexts in tests is more verbose than just
passing in path prefix values directly.
