Right now, in the WiredTiger integration layer, we generate a new global cursor epoch and close all cursors that are returned to the cache on encountering a WT_BUSY attempting to drop a specific ident. Change closeAllCursors to only close cursors on the idents that require dropping.

This is expected to significantly help users with large numbers of collections.

depends on

SERVER-27345 reclaim inactive WT sessions on calling closeAllCursors

Closed

WT-3369 WT_CURSOR->uri should always match the URI used to open the cursor

Closed

is depended on by

SERVER-27348 Only retry dropping idents on WiredTiger after closing cursors on them

Closed

is duplicated by

SERVER-29024 Collection drop slows/stalls down database operations

Closed

related to

SERVER-30426 dropDatabase very slow due to repeated calls to closeAllCursors
