check_esx_datastore_snmp V2 & V3

Project Notes

Basically I took existing check_esx_datastore_snmp and modified it to be able to work with VMware ESXi, 6.7.0, 15160138 and VMware ESXi, 7.0.2, 17867351

Pre-req for enabling SNMP on ESX was the easiest way found over here (btw, I had to enable V2 at first and then V3 on ESXi, otherwise hashes weren't correct):
