What is the task about?

This task is about implementing a new RSTUF Key Vault Service which supports AWS KMS.

This functionality enables the RSTUF users to use the online key from AWS KMS.
The Security Systems Lib creates a Signer which supports AWS KMS.

For this task we can introduce to the RSTUF Development KMS localstack for development and tests

For this issue to be fixed it's better we wait for a new version of securesystemslib which will include the new AWSSigner they have introduced post their 0.28.0 release.

Is there anything missing after having merged #452?

[MVrachev]

I don't think there is.
Let's close it. If there is a need for a similar issue we can always restore it or create a new one.
