Describe the bug
After upgrade to Terraform 0.12, the vra7 provider can not be instantiated.

To Reproduce
Steps to reproduce the behavior:

1. upgrade to Terraform v0.12.0

3. Error: Failed to instantiate provider "vra7" to obtain schema: Incompatible API version with plugin. Plugin version: 4, Client versions: [5]
4. terraform init -upgrade

Provider "vra7" not available for installation.

A provider named "vra7" could not be found in the Terraform Registry.

This may result from mistyping the provider name, or the given provider may
be a third-party provider that cannot be installed automatically.

In the latter case, the plugin must be installed manually by locating and
downloading a suitable distribution package and placing the plugin's executable
file in the following directory:
    terraform.d/plugins/windows_amd64

Terraform detects necessary plugins by inspecting the configuration and state.
To view the provider versions requested by each module, run
"terraform providers".

Error: no provider exists with the given name

> terraform providers
.
└── provider.vra7

Expected behavior
The vra7 provider works with the upgraded Terraform application.
