Mention the possible meaning (usage) of internal urls

[xasima]

Besides documenting the standards ostrich commands (that is presented on project description).

ping
reload
shutdown
quiesce
stats
server_info
threads
gc

please mention in more details the possible meaning (usage) of internal urls

/report/
/pprof/heap
/pprof/profile
/pprof/contention
/tracing
/health
/graph/
/graph_data
/quitquitquit
/abortabortabort

It seems that html /report (versus json /stats), health (versus admin /ping), and graph_data may brings additional information for developers / integration.
