Add output for "?auto" version of server-status
to proxy status, mod_ssl session cache info,
mod_cache_socache and the status hook of the
individual socache implementations.


Followon to r1671397 for proxy server-status
in auto mode:
- don't show HTML legend
- Show correct worker name


More followon to r1671397 for proxy server-status
in auto mode:
- remove remaining HTML markup

Add more data to "?auto" view of server-status.

Although mod_status source code calls this the
"short_report", the docs and the API flag call
it "Machine Readable" resp. "STAT_OPT_AUTO".
So IMHO the data shown should be on par with
the html version.


Followon to r1671396:
Remove unwanted redundant output introduced
by that commit.


Followon to r1671396: add misiing newline in
new server-status output.
