### Description of the change Follows on from #6620, uses the grpc Client to check if we can find repos for an OCI registry. While there I improved a couple of other things regarding the validation: - a context.Context can (and must) now be passed through to the validation (we should always pass the request context through subsequent requests); and - the getValidator function is now a method so that the different validators can have custom data set (such as the OCI catalog address, or the repo client getter). I've added a basic test double grpc service for the OCI catalog to use here in tests, and will undoubtedly improve this test double when adding the actual sync functionality to use the OCI catalog service next. ### Benefits OCI Catalog service can be used to check an OCI Registry, without impacting current behaviour. ### Possible drawbacks None that I'm aware of. ### Applicable issues - ref #6263 ### Additional information I'll test IRL locally and update here: Logs showing the fallback when the OCI catalog is not running: ``` E0816 03:49:15.487354 1 repositories_validation.go:354] unable to query OCI Catalog service at ":50061": error querying OCI Catalog for repos: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing: dial tcp :50061: connect: connection refused" E0816 03:49:16.462758 1 utils.go:400] unable to get catalog manifest: GET request to [https://registry-1.docker.io/v2/bitnamicharts/charts-index/manifests/latest] failed due to status [401]: {"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":[{"Type":"repository","Class":"","Name":"bitnamicharts/charts-index","Action":"pull"}]}]} E0816 03:49:16.462894 1 repositories_validation.go:52] Failed repository validation validation: &{Code:400 Message:unable to determine the OCI catalog, you need to specify at least one repository} ``` and verified I can add the Bitnami catalog using the OCI `https://registry-1.docker.io/bitnamicharts` . That is, it passes validation and gets added. It doesn't yet sync - that'll be the next PR. --------- Signed-off-by: Michael Nelson <minelson@vmware.com>

Description of the change
First part of integration work to update the OCI repo support to use the oci-catalog service. This PR refactors the existing repository validation to remove the assumption of an
HTTPValidator(since the gRPC validation doesn't use an httpclient etc.)Benefits
Step towards adding grpc validation for OCI repositories using the new service.
