Port changes from the downstream docs to upstream (RGW installation and RGW quick)

Since you are touching most of the rgw docs anyway, could you also add the rgw frontends option in the config-ref as well. (Bug: http://tracker.ceph.com/issues/13670)

[theanalyst]

Possibly you could say if you use iptables as a firewall, execute, instead of For Ubuntu? (Since other distros may use iptables as firewall as well?)

@baruza Overall looks good.. just add a couple of options I mentioned to config-ref page as well and minor nits. Thanks!

[baruza]

@theanalyst, thank you for the review - I've fixed all the things you mentioned (9b078cf) except for documenting the rgw frontend option in config-ref. Could you advice me to whom I should ask about that? (since I don't know anything about it)

@baruza you have a 'Signed-of-by' in this commit: 7eca3a9

But it should really be: 'Signed-off-by'

@alfredodeza oh, sorry my mistake - is it possible to amend already pushed commit? Or how can I fix it?

[theanalyst]

@baruza It is just a file in the same rgw folder ..ie. config-ref.rst https://github.com/ceph/ceph/blob/master/doc/radosgw/config-ref.rst#ceph-object-gateway-config-reference here just add the option rgw frontend and give the default value, and type etc.
