Bump terraform version to 0.12.25

[felddy]

🗣 Description

Terraform 0.12.25 (May 13, 2020)

NOTES:

• backend/s3: Region validation now automatically supports the new af-south-1 (Africa (Cape Town)) region. For AWS operations to work in the new region, the region must be explicitly enabled as outlined in the AWS Documentation. When the region is not enabled, the Terraform S3 Backend will return errors during credential validation (e.g. error validating provider credentials: error calling sts:GetCallerIdentity: InvalidClientTokenId: The security token included in the request is invalid). (#24744)

ENHANCEMENTS:

• backend/s3: Support automatic region validation for af-south-1 (#24744)
• backend/remote: Add support for force push to remote backend (#24884)

BUG FIXES:

• core: Destroy provisioners should not evaluate for_each expressions (#24163)
• core: Fix races in GetVariableValue (#24599)
