Move id_minter service to lambda

[kenoir]

We should look at moving the id_minter as the next service to move from ECS to lambda as it has the novel characteristic of managing database connections.

We have proven the lambda approach elsewhere, so going forward we will presume that extended parallel running of services and full reindexes to prove behaviour are not required. We should still test in branches, and implement parallel running but in order to expedite releasing the new implementation we can avoid the creation of a new pipline.
