feat(client): support tls scheme

[IzioDev]

• tighten tonic features to the required minimum
• validate provided URI before initializing the tonic client. additionally: add opinion on how URI should be constructed regarding authority - it must be present, URI like /my-path aren't supported (not a regression).
• allow more valid URI forms: 127.0.0.1, http://127.0.0.1, https://example.com, http://user:password:port/my/path?arg=1
• add TLS support, using the native certificate store, on this tonic version (0.12.3) the provider is ring (crate) and it seems there is no way to change it. on newer versions, one can chose among the provided ones or provide a custom.
• grpc:// usage has been removed as it's non std
