swift proxy healthcheck function is undocumented

[Tom Fifield]

Swift proxy's filter:healthcheck is undocumented in the manual. This is a handy filter for monitoring and should be in there somewhere

Healthcheck middleware used for monitoring.

If the path is /healthcheck, it will respond with “OK” in the body

GET(req)

    Returns a 200 response with “OK” in the body.

The following configuration options are used:

Variable Service module Default
log_facility proxy_server filter:healthcheck 'LOG_LOCAL0'
log_level proxy_server filter:healthcheck 'INFO'
log_name proxy_server filter:healthcheck 'healthcheck'

    Adding additional features section to swift doc

    Adds a new section for additional swift features previously
    undocumented, including: healthcheck, domain remap, cname_lookup,
    and tempurl.

    Information on these can be scant - so I see this patch as more of
    a starting point which can be added to as more becomes known.
