Disk size monitoring unexcepted behaviour

See original GitHub issue

Description VM disk size monitored only one time after opennebula service restart using tm/driver/monitor script.

Sat Dec 29 11:24:24 2018 [Z0][ImM][D]: Datastore 3par_system (0) successfully monitored.
Sat Dec 29 11:24:24 2018 [Z0][VMM][D]: VM 97 successfully monitored: DISK_SIZE=[ID=0,SIZE=4242]
Sat Dec 29 11:25:09 2018 [Z0][InM][D]: Host tst.lin.fedora.host (0) successfully monitored.
Sat Dec 29 11:25:09 2018 [Z0][VMM][D]: VM 97 successfully monitored: STATE=a CPU=0.0 MEMORY=807324 NETRX=6317550576 NETTX=127931671 DISKRDBYTES=285341508 DISKWRBYTES=6207442432 DISKRDIOPS=8641 DISKWRIOPS=15705
Sat Dec 29 11:29:25 2018 [Z0][ImM][D]: Datastore 3par_system (0) successfully monitored.

As you see in logs, first time system ds is monitored log is followed by VM 97 successfully monitored: DISK_SIZE=[ID=0,SIZE=4242], next systems ds monitorings are without VM disk size parsing.

Expected behavior Disk size monitoring each time system datastore is monitored.

Monitor script parses disk usage stats only on each 10th run, so practically every 50minutes

Few proposals:

this variable should be configurable
most important is adding additional argument when calling ds monitor script to inform, that should NOT collect data about disk/snapshot usage, because it cost resources and it is used only every 10th run.
