updating the swift configuration files

Includes now all possible options found on latest 1.8.X configs so that users
are able to view all that is available without having to check manpages. Manpages
still contain more details though.
Disabling verbose logging

Although it is helpful on some cituation to troubleshoot swift/memcache
related issues, this should only be turned on when needed. If one wants
to have it on by deafult, logratation needs to be setup for /var/log/memcache.log
otherwise the logging data could grow largely and fillup the partition.
memcache script updated to get listening ip

Updated this script to get the proper IP that memcache is
listening to instead of assuming 127 is the one. Also changed
some variables to lowercase.

This closes https://github.com/rcbops-cookbooks/swift-private-cloud/issues/21
