tsdb/agent: Fix deadlock from simultaneous GC and write (#10166) 
* tsdb/agent: Fix deadlock from simultaneous GC and write

This commit fixes a potential deadlock where storing in-memory series
references could deadlock with a WAL GC cycle.

Signed-off-by: Robert Fratto <robertfratto@gmail.com>

* add missing license header

Signed-off-by: Robert Fratto <robertfratto@gmail.com>

* order local imports

Signed-off-by: Robert Fratto <robertfratto@gmail.com>

* align deadlock testing with discovery/manager_test.go method

Also prevents GCs from running concurrently, which could also cause a
deadlock (even though it's currently impossible for two GCs to run
concurrently).

TSDB

GoPkg

This directory contains the Prometheus TSDB (Time Series DataBase) library, which handles storage and querying of all Prometheus v2 data.

Due to an issue with versioning, the "latest" docs shown on Godoc are outdated. Instead you may use the docs for v2.31.1
