Update ClientConfig Base class

[rihp]

Initially we had a ClientConfig base class with a list of Environments, and a list of interfaces,

@dataclass(slots=True, kw_only=True)
class ClientConfig:
    envs: List[Env] = field(default_factory=list)
    interfaces: List[InterfaceImplementations] = field(default_factory=list)
    resolver: IUriResolver

Both of these fields are now being changed to a Dictionary for simpler client configuration.

@dataclass(slots=True, kw_only=True)
class ClientConfig:
    envs: Dict[Uri, Env: Dict[str, Any]] = field(default_factory=dict) 
    interfaces: Dict[Uri, List[Uri]]
    resolver: IUriResolver

This changes break some of the client functionality, working on those fixes now
