Using the modules with Terraform 0.15 can fail due to use of 'sensitive' output in metadata

[memes]

Describe the bug

Terraform 0.15 fails to deploy BIG-IP from these modules due to interpretation of metadata output as containing sensitive information. Fix will be to explicitly mark metadata map output from metadata sub-module as sensitive, even though it does not contain sensitive information.

Terraform modules used

• BIG-IP standalone
• BIG-IP HA
• BIG-IP CFE

GCP environment

• Standalone project (default)
• Shared VPC Host project
• Shared VPC Service project
• Integration with serverless (Cloud Functions, Cloud Run, App Engine, etc.)

Any other details we need to know?

Reproducing the issue

Deploy BIG-IP from this module.
