 Description   

Currently, the lock mode is shown on the resource node, like the following, but the accurate representation should show the mode on edge since a lock can be acquired by different threads in multiple modes, e.g. IS and IX. Showing the lock mode of pending lock requests will also be helpful.

    "Lock 0x7f1546492700 (mongo::MODE_IX)" [label="Lock 0x7f1546492700 (mongo::MODE_IX)" ]
