Configure Python logging level when debug flag is specified; add debug logs to bake command

[lgarber-akamai]

📝 Description

This pull request updates the --debug flag to additionally set the Python logging package's log level to DEBUG. This allows users to more easily diagnose issues with underlying dependencies (e.g. urllib3) and introduces a standardized logging format we can use for debugging.

This pull request also introduces various log statements to the linode-cli bake command, which should make build issues easier to diagnose in CI.

✔️ How to Test

The following test steps assume you have pulled down this PR locally and run make install.

Unit Testing

make test-unit

Manual Testing

1. Attempt to re-bake the OpenAPI spec:

make bake

2. Ensure the output contains debug lines similar to the following:

DEBUG:linodecli.cli:GET /{apiVersion}/vpcs/{vpcId}/subnets/{vpcSubnetId}: Attempting to generate command for operation
DEBUG:linodecli.cli:GET /{apiVersion}/vpcs/{vpcId}/subnets/{vpcSubnetId}: Successfully built command for operation: command='vpcs subnet-view'; summary='Get a VPC subnet'; paginated=False; num_args=0; num_attrs=8

3. Run an arbitrary command using the --debug flag:

linode-cli linodes create --debug --type g6-nanode-1 --region us-mia --label test

4. Ensure urllib3 debug information is displayed alongside the API request/response data.
