Chris Marchbanks c5b3f0221f Decode WAL in Separate Goroutine (#6230) 
* Make WAL replay benchmark more representative

Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>

* Move decoding records from the WAL into goroutine

Decoding the WAL records accounts for a significant amount of time on
startup, and can be done in parallel with creating series/samples to
speed up startup. However, records still must be handled in order, so
only a single goroutine can do the decoding.
