Create PierianDx permission stack

[alexiswl]

Problem

Currently we're generating a new pieriandx session token every five minutes (stored in AWS secrets manager) courtesy of the cttso-ica-to-pieriandx stack.

Comprises the following

• Has two secrets - an API Key (just a username password combination updated every second month) and an access token (expires after 5 mins)
• One lambda that has read access to the API Key and read/write access to the access token. Lambda determines if the access token is valid / not expired. If the access token is near expired (within 30 seconds), access token is regenerated and stored in AWS secretsmanager, the new access token is returned to the user.
• One shell script to update the pieriandx username password combination.

This service can be used by the cttso-ica-to-pieriandx stack as well as the new v2 pieriandx submission service.

Perhaps, check it out OrcaBus TokenService stack umccr/orcabus#197 and, links pointer in umccr/orcabus#127

Thanks @victorskl, I'm using the icav2 credentials stack as my template here. Not as simple as the key rotation here since token expires every 30 minutes!

O, 30 minutes... is a bit brutal.! 😭
