IAM, STS | Improve Log Printing Before Throw Error of NotImplemented

[shirady]

Describe the Problem

Currently, when using an action that is not listed in the actions supported in IAM (which is based on STS implementation) we don't have a log printing, and it is harder to debug if external application uses the code base without us knowing exactly what it is performing.

Explain the Changes

1. In the function parse_op_name add log printing with additional info to help debugging (in IAM and STS).

Issues:

1. The printing of IAM REQUEST is printed after parsing, so we will not see all the information when using a supported action (link).

Testing Instructions:

1. Create an account with noobaa CLI: sudo node src/cmd/manage_nsfs account add --name <account-name> --new_buckets_path /Users/buckets/ --access_key <access-key> --secret_key <secret-key> --uid <uid> --gid <gid>
   Note: before creating the account need to give permission to the new_buckets_path: chmod 777 /Users/buckets/.
2. Start the NSFS server (using debug mode and the port for IAM): sudo node src/cmd/nsfs --debug 5 --https_port_iam 7005
3. Create the alias for IAM service:
   alias nc-user-1-iam='AWS_ACCESS_KEY_ID=<access-key> AWS_SECRET_ACCESS_KEY=<secret-key> aws --no-verify-ssl --endpoint-url https://localhost:7005'
4. Use unsupported action: nc-user-1-iam iam create-group --group-name Admins expect to see:

"[ERROR] core.endpoint.iam.iam_rest:: IAM parse_op_name - NotImplemented CreateGroup post /"
