docs: Convert alias and bridge to rst

Hi Dave,

Here is my first attempt at working on converting docs in Documentation/networking to rst format. I've picked a couple of trivial ones to start with. If there is anything extra I can do to make your life easier during documentation conversion please say. (Also if there is some reason that it would be preferable to _not_ embark on this task please say :)

This set does not make any changes to the converted files apart from formatting.

thanks,
Tobin.

v2:
- remove incorrect patch from set (changing 'Indices' indentation)
