The only section that still aplies was the one on the default storage
directory so those docs seem obsolete.
We'll probably have a similar page on the new storage but we'll only
find out what caveats etc. we'll have to point out as we get people
reporting problems or notable behavior.
Go automatically configures the number of used threads appropriately
and tweaking it is no longer relevant for a basic setup of Prometheus.
The baseline consumption tied to the storage layer no longer applies.
In order to provide documentation for each individual version, this
commit starts moving Prometheus server specific documentation into the
repository itself.
