adding support for OpenStack
read files in binary mode when calculating checksums, this ensures equality across platforms
always fall back to just using the uid and gid if pwd and grp won't work
Use 'ip -o addr' instead of ifconfig for parseable output

The 'ifconfig' command is deprecated, and the 'ip' command should
be used instead for multiple reasons. This is also a more easily
parseable format.
Change get_interface_name to support arbitrarily named interfaces

Due to support for biosdevname, we now have to look at interface
types rather than names in order to determine whether an interface
is interesting for this plugin.
Collect ring, coalesce, and pause attributes of interfaces.

These are very useful items to have in general in order to see
the configuration of systems. They are performance impacting
parameters.
Add generated files to .gitignore
