0.7.0

New this release:

• Renames the ops-manager-and-director-subnet to management-subnet. This is a backwards-incompatible change.
• Ensures that the root DB user password is set to a non-default value.
• Ensures google_compute_ssl_certificate uses create_before_destroy to prevent issues when updating the certificate.
• Adds new databases for the ERT: account, networkpolicyserver, and nfsvolume.
• Adds service_account_email as an output property.
• Outputs subnet CIDRs as a list to bring this property into alignment with the other terraforming-IAAS repos.
