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.

Add a new section to the PG troubleshooting section that covers the most
common problems reported when an erasure coded pool fails to properly
map PGs to enough OSDs.

The in-tree Hadoop shim was a combination of libcephfs wrapper, and the
bits to support Hadoop. This has been replaced by src/java that
implements generic libcephfs wrappers, and externally, the hadoop shim
(see docs).

Logging was variously described in the ceph configuration document,
a configuration reference, and a section in operations. Since
logging and debugging are generally used with troubleshooting,
I consolidated the docs and placed them in the troubleshooting
section. Also fixed the example and provided additional detail.
