cdot aggr troubleshoot with debug vreport

If there is an inconsistency between VLDB and WAFL on a local node,
you can fix that with "debug"

Create an aggregate in the nodeshell
This aggregate will be known in WAFL but not in VLDB

cl1::*> node run -node cl1-01
Type 'exit' or 'Ctrl-D' to return to the CLI
cl1-01> options nodescope.reenabledcmds "aggr=create,destroy,status,offline,online"
cl1-01> aggr create aggrwafl 5
Creation of an aggregate with 5 disks has completed.

Create an aggregate in the clustershell and remove it from WAFL.
This aggregate will then be known in VLDB but removed from WAFL.

cl1::>aggr create rdbaggr -diskcount 5 -node cl1-01
cl1::> node run -node cl1-01
Type 'exit' or 'Ctrl-D' to return to the CLI
cl1-01> aggr offline rdbaggr
Aggregate 'rdbaggr' is now offline.
cl1-01> aggr destroy rdbaggr
Are you sure you want to destroy this aggregate? y
Aggregate 'rdbaggr' destroyed.
cl1-01> exit
logout

Run dbug vreport.

cl1::> set diag
cl1::*> debug vreport show

Fix VLDB ( aggregate will be added to VLDB )
cl1::debug*> debug vreport fix -type aggregate -object aggrwafl(8e836c6d-76a0-4202-bb40-22694424f847)

Fix VLDB ( aggregate will be removed from VLDB )
cl1::debug*> debug vreport fix -type aggregate -object rdbaggr
cl1::debug*> debug vreport show
This table is currently empty.
Info: WAFL and VLDB volume/aggregate records are consistent.
