of numbers.

objectstore_tool: keep all json object representation

For erasure coded pools to be tested, the json object representation
must be preserved for all PG because they are all different. The
internal representation is changed from

   db[name]["pgid"] = pg
   db[name]["json"] = objjson

to a per pg map:

   db[name].setdefault("pg2json", {})[pg] = objjson

and the rest of the code is modified to adapt accordingly.

restoring it.

objectstore_tool: encapsulate into a function

Move code out of the task into function. Also remove the "REP" specifics
from helper functions that could also be used for erasure coded pools.

objectstore_tool: add pgnum option

Instead of hardcoding 12 use a configuration option that defaults to
12. It is handy during development to lower the number to 4 and speed up
the test cycle.
