Richard (Rick) Hawkins 2c4bf81464 Added discoverable capabilities.

Swift can now optionally be configured to allow requests to '/info',
providing information about the swift cluster.  Additionally a HMAC
signed requests to
'/info?swiftinfo_sig=<sign>&swiftinfo_expires=<expires>' can be
configured allowing privileged access to more sensitive information
not meant to be public.

Discoverability

Swift can optionally be configured to provide clients with an interface providing details about the installation. If configured, a GET request to /info will return configuration data in JSON format. An example response:

{"swift": {"version": "1.8.1"}, "staticweb": {}, "tempurl": {}}

This would signify to the client that swift version 1.8.1 is running and that staticweb and tempurl are available in this installation.

There may be administrator-only information available via /info. To retrieve it, one must use an HMAC-signed request, similar to TempURL. The signature may be produced like so:

swift-temp-url GET 3600 /info secret 2>/dev/null | sed s/temp_url/swiftinfo/g
