Target subtypes must now implement another repository hook to validate
any CredentialLibraries that are being added/set. This allows for
subtypes to determine the valid set of CredentialLibraries.
For tcp.Targets only CredentialLibaries with
credential.ApplicationPurpose are allowed. If any other purpose is
provided an error is returned.
This change removes the hard-coded credential purpose for the Credential
Libraries. It also moves the logic of creating CredentialLibraries from
CredentialSources out of the repository and into the targets.Service.
This refactor will allow for additional credential purposes to be
supported in both the service and the repository.
For the target Repository's Create method, the options of
WithHostSources and WithCredentialSources where never used by the
targets.Service. As such the repository does not need to support these
options.

Now that subtypes are registered via sub-packages, this TargetType is
not needed and should not be used. This removes it and updates the
target.Repository and targets.Service to use the updated code.
This was missed in eac433f7ff.
This moves all of the tcp target functionality into a tcp package. It
also establishes a Register function in the target package to allow
specific target types to be registered at initilazation time. When
registering, a target type needs to provide its Subtype, as well as some
RepositoryHooks that are used by the target Repository.
