PATCH: extend man page mount.ceph.8 with available options

[Thomas Mueller <thomas@chaschperli.ch>]

hi

i was searching the mount options in the code. i've extended
the man page of mount.ceph.8 with my findings.

* i've excludede fsidmajor and fsidminor as i really don't known 
what they do 

* excluded monport as it seems not to be use anywhere in the code.

* for dirstat and nodirstat i don't know which of the both
is enabled by default.

* rbytes/norbytes - same as for dirstat and I don't know what the
switch does.

* "don't share client with other sbs" - what does "sbs" mean? (found
this one in the code)
