Remove TS item on setting cinder simple scheduler

Browse Source 
The Chance and Simple schedulers of cinder are now deprecated, setting
them will just default to the Filter scheduler anyway. This patch
deletes a Troubleshooting section advising users to set the Simple
scheduler (specifically,
doc/admin-guide-cloud/section_ts_failed_sched_create_vol.xml).

Partially implements bp: deprecate-chance-and-simple-schedulers
