Removal of vcenter is preventing certain tasks in the vcenter role

[richardboswell]

The following modules were pulled from the manifest and therefore the associated tasks are failing:

• vcenter_add_nfs_ds: vcenter/tasks/storage.yml --> Add NFS datastore to OOB ESX hosts, Add NFS datastore to IB ESX hosts, Remove NFS datastore from OOB ESX hosts, Remove NFS datastore from IB ESX hosts
• vcenter_datacenter: vcenter/tasks/create_datacenter.yml via templates/create_datacenter.yml.j2--> Create Datacenter, vcenter/tasks/destroy_datacenter.yml via templates/destroy_datacenter.yml.j2 --> Destroy Datacenter
• vcenter_addhost: vcenter/tasks/esxhosts.yml --> Add ESX hosts to OOB cluster, Add ESX hosts to IB cluster, Remove ESX hosts from OOB cluster, Remove ESX hosts from IB cluster

The commit that removed these modules should be reverted OR if they were meant to be removed the new modules/updated tasks need to be committed after successful testing.
