feat: Add logging

[diego-ojeda-binbash]

Description

Add logging support by introducing 2 new variables:

• tunnel1_log_options
• tunnel2_log_options

Motivation and Context

Logging is very useful for troubleshooting.

Breaking Changes

There shouldn't be any as the new variables have safe defaults.

In me-central-1 where logging is not enabled this is causing update on each apply:

      + tunnel1_log_options {
          + cloudwatch_log_options {
              + log_enabled       = (known after apply)
              + log_group_arn     = (known after apply)
              + log_output_format = (known after apply)
            }
        }

      + tunnel2_log_options {
          + cloudwatch_log_options {
              + log_enabled       = (known after apply)
              + log_group_arn     = (known after apply)
              + log_output_format = (known after apply)
            }
        }

Is there a way to disable it?
