Write Terraform CLI logs to container stdout

[suramasamy]

Description of your changes

Added optional field enableTerraformCLILogging to the Workspace resource to enable writing of Terraform CLI logs to the container stdout in JSON format to assist with debugging and to view detailed information about Terraform operations.

Fixes https://github.com/upbound/provider-terraform/issues/163

I have:

• [x] Run make reviewable to ensure this PR is ready for review.
• [x] Run make e2e with UPTEST_EXAMPLE_LIST="examples/workspace-enable-logging.yaml"

How has this code been tested

• On the local cluster, applied the Workspace resource present in the examples workspace-enable-logging.yaml
• Observed that the container logs has the expected Terraform Plan and Apply logs
• Made changes to the Workspace YAML and re-applied
• Observed that the container logs are updated with new Terraform Plan and Apply logs
• Changed enableTerraformCLILogging to false, made few other Terraform code changes in the Workspace YAML and re-applied
• Observed that the container logs doesn't have the new Terraform Plan and Apply logs
• Toggled enableTerraformCLILogging to true and re-applied the Workspace
• Deleted the Workspace resource, Observed that the container logs has the expected Terraform Destroy logs.
