[AAF] Allow to choose which subcomponents to run

[AAF] Allow to choose which subcomponents to run

AAF has 4 sub components underneath:

- AAF Authz (for generating, signing the certificates)
- AAF Hello (example on how to use AAF Authz)
- AAF SMS (for storing sensible values in Vault)
- AAF SSHMS (for using TPM devices)

This commits allows to choose which components will be used by default.
As SSHMS is not updated for a while and AAF Hello is an example, we also
disable them.
