Setting dashboard CPU, memory, and rootfs

The dashboard's CPU, memory, and rootfs sizes can be modified by editing the cluster control facts from the dashboard CLI via the following files:

### If the files are not present under the node-dashboard directory, they will need to be created

root@hypercloud-dashboard:~# cat /var/run/cluster-control/facts/node-dashboard/cpu 
16
root@hypercloud-dashboard:~# cat /var/run/cluster-control/facts/node-dashboard/memory 
16384
root@hypercloud-dashboard:~# cat /var/run/cluster-control/facts/node-dashboard/rootfs 
8192

After changing the values of the files above, the dashboard will automatically restart and apply the modifications.
