Code Issues Proposed changes

Resync charm helpers 

Add support for OpenStack Newton and Ocata.

Rework version detection code to just match on major version for
OpenStack projects using semantic versioning.

Provide fallback version detection based on major.minor versions
for swift packages.

Rework config-flags support helpers.

Fix is_ip function to correctly detect both IPv4 and IPv6 addresses.

"""Parses config flags string into dict.
This parsing method supports a few different formats for the config
flag values to be parsed:
1. A string in the simple format of key=value pairs, with the possibility
of specifying multiple key value pairs within the same string. For
example, a string in the format of 'key1=value1, key2=value2' will
return a dict of:
{'key1': 'value1',
'key2': 'value2'}.
2. A string in the above format, but supporting a comma-delimited list
of values for the same key. For example, a string in the format of
'key1=value1, key2=value3,value4,value5' will return a dict of:
{'key1', 'value1',
'key2', 'value2,value3,value4'}
3. A string containing a colon character (:) prior to an equal
character (=) will be treated as yaml and parsed as such. This can be
used to specify more complex key value pairs. For example,
a string in the format of 'key1: subkey1=value1, subkey2=value2' will
return a dict of:
{'key1', 'subkey1=value1, subkey2=value2'}
The provided config_flags string may be a list of comma-separated values
which themselves may be comma-separated list of values.
