no eligible ssds in vsan_claim.py

[displague]

I captured the following log output while attempting to provision this module with the following non-default, Packet device, settings:

esxi_size       = "c3.medium.x86"
router_size     = "c2.medium.x86"
esxi_host_count = "1"
facility        = "dfw2"

Traceback (most recent call last):
  File "vsan_claim.py", line 97, in <module>
    smallerSize = min([disk.capacity.block * disk.capacity.blockSize for disk in ssds])
ValueError: min() arg is an empty sequence

By adding a print statement in vsan_claim.py, we can see that none of the ssd=True disks were status='eligible') (only one disk is shown here, for brevity. Each of the three included the error message that the disk contained existing partitions):

88 diskmap = {host: {'cache':[],'capacity':[]} for host in hosts}
89 cacheDisks = []
90 capacityDisks = []
91
92 for host in hosts:
93     print(repr(hostProps[host]['configManager.vsanSystem'].QueryDisksForVsan())) # added for debugging
94     ssds = [result.disk for result in hostProps[host]['configManager.vsanSystem'].QueryDisksForVsan() if
95         result.state == 'eligible' and result.disk.ssd]
97     smallerSize = min([disk.capacity.block * disk.capacity.blockSize for disk in ssds])

I ran into a similar error on equinix/terraform-metal-vsphere#19 caused by having 1 ESXI compute noted.
