11fef2275d doc: recommend opening entire 6800-7300 port range 
Prior to this commit, the Network Configuration Reference guide and
Troubleshooting guide recommended opening a number of ports that were
unique to the number of daemons that we ran.

This doesn't really cover all use cases. Users can easily restart
daemons in ways that cause the daemons to bind to higher ports. This
leads to OSDs or MDSs binding to ports that are firewalled.

Update the Network Configuration Reference guide and Troubleshooting
guides to simply recommend that users open all the ports between 6800
and 7300 on their OSDs and MDSs.

808ad25a28 doc: Removed fragmented logging info. Consolidated into one doc. 
Logging was variously described in the ceph configuration document,

I consolidated the docs and placed them in the troubleshooting
section. Also fixed the example and provided additional detail.
