Engineering Ticket Description:

Allow access to the list of active cursors.

This should allow returning something like this:

> db.runCommand("listCursors")
{ ok:1.0,
 cursors: [
    {
	id:..., 
	ns:..., 
	query:..., 
	client:..., 
	created:...., 
	lastAccess:..., 
	noTimeout:.., 
	timeoutInMS:..., 
	runningMS:...,
	yieldNum:...,  
	user:..., 
	nReturned:..., 
	nPosition:..., 
	...} //recordStats/locks/curOp-info/etc
  ]
}

This command should be user-aware and only return cursors for the active user.

Paramters:

name	value	desc/behavior
filter	<any query filter>, {id:###}	This should allow a filter/match param to reduce the total set of cursors returned.
ns/db		filters to this ns/db – command name value is the default for this if not true-ish
user	<current>	This command should be user-aware and only return cursors for the active user. Optionally this should allow overriding to return all user info if the user has privs
