* maint: update module to pdk 3.0.0

this also updates the linter to use the pdk docker image

* maint: fix ci linting issues

* maint: update rspec ci testing

* Accept Sensitive for CID

We pull the Value for CID from our Secret-Vault, as we consider CID as
worthy of Protection.  Our Secret-Vault yields Sensitive[String].  In my
Opinion Writers of Profile-Modules should not be bothered with handling
Values of Type Sensitive.  Passing them over to the Component-Modules,
(like “falcon”) should “just work”.

- let init.pp accept CID of Datatype Sensitive[String]
- do the Unwrap at the latest possible Location

* update rspec tests
