remove a spurious wait that could get us into trouble

it's not really clear that this wait is useful for anything
except generating bugs when we've done terible things to the
image during this test. Removing it as unneeded.

Add a control point for floating IP assignment

In the basic network scenario test, the test for accessiblity via the
floating IP stands a very good chance of failing because the attempt to
connect begins before the system has had a chance to associate the
floating IP address.  While an extended delay does signify a performance
issue for those types of operations, the timing of the test can be
adversly affected by other factors (e.g. parallel tests, loaded test
  system). If it is extreme the check for the IP address will fail the
test as well. This addition also covers a loophole in the test where
the connectivity would work but the metadata that is provided through
the client call is not updated properly.

An additional small fix in manager.py resolves an issue when a client
API uses mixed or lower case for status strings (e.g. cinder).

There isn't a specific bug that this modification addresses.

Add whitelist entry for s-proxy 'Timeout talking to memcached'

According to John Dickinson:

"This isn't an error. It's logged at an error level because it may hint
at other problems, and it's something an operator needs to know about,
but it is not an unhandled failure condition. (Think of it similarly how
in swift a server being down is an "error", but it's something that
swift seamlessly works around.)"

Set pipefail for wrapper scripts

Previously if the testr list command was failing subunit2py would
return a 0 making the test runs that use the pretty_tox scripts also
return 0 despite testr actually failing. This commit gets around this
condition by setting pipefail in the pretty_tox scripts to ensure that
we actually fail.
