Library - Validate CBOR structs according to the cddl schema for nodes/models misc

[nazmulidris]

The ockam_api crate exchanges many structs with the Controller. Those structs are serialized using CBOR and should conform to the cddl schema.

Currently there are only a handful of structs tested for conformance to the schema:

• project (and related structs)
• space (and related structs)
• subscription (and related structs)

The purpose of this issue is to complete the testing by:

• adding more quickcheck properties similar to the ones above
• adding missing schema.cddl definitions where necessary
• additionally remove the lifetime annotations on structs, like this one (and replace CowStr<'a> with String)

To the following list of structs:

• nodes/models/base/NodeStatus
• nodes/models/credentials/GetCredentialRequest
• nodes/models/credentials/PresentCredentialRequest
• nodes/models/flow_controls/AddConsumer
• nodes/models/forwarder/CreateForwarder
• nodes/models/forwarder/ForwarderInfo
• nodes/models/identity/LongIdentityResponse
• nodes/models/identity/ShortIdentityResponse
• nodes/models/policy/Policy
• nodes/models/policy/PolicyList
• nodes/models/policy/Expression
