[wsgi] Duplicate config options relating to max Content-Length

[Kurt Griffiths]

These are no longer needed in light of our redifinition of max message and metadata sizes, and indeed have been the source of some confusion and bugs.

# Maximum Content-Length allowed for metadata updating and
# message posting.
;metadata_max_length = 65536
;content_max_length = 262144

    fix(wsgi): Cleanup limit config options

    This patch contains several misc. changes to queue, message, and
    claim limits to reduce confusion and bring the implementation in
    line with the v1 spec.

    1. Removed a couple of WSGI driver config options that are
    no longer needed now that we have redefined (and simplified) how
    we constrain message and metadata size.

        metadata_max_length = 65536
        content_max_length = 262144

    2. Renamed options to be more readable and consistent
    3. Moved options to [transport] section
    4. Made max messages that can be claimed its own setting, to reduce confusion
    5. Removed enforcing an upper limit on the number of messages that can be
    posted; this was never in the spec, and appears to be gold-plating. Now, the
    only upper limit is max_message_size.
    6. Removed the check on the size of a create claim request since (1) it is
    not part of the API spec, and (2) sanity-checks like that are best done by
    the web server, before a request even touches the app.
    7. Migrated limits for storage driver interface params to static values,
    since those defaults define the static contract between transport and
    storage drivers.
    8. Wrapped validation error messages in gettextutils._, and converted them
    to use .format instead of %.
