    Change `RedisClientError` from enum to struct · 06471a2a

    Motivation:
    
    The current state of Swift does not leave room for library evolution of enum types used for `Error`.
    
    To avoid having to increment Major SemVer to add a new error case that might be needed to fix a bug, the `enum-like struct` idiom should be used.
    
    Ideally this idiom will disappear, when Swift provides a way for Swift Packages to have a "library evolution" capability.

    Modifications:
    
    - Change: `RedisClientError` to be struct with private enum value
    
    Result:
    
    Should new error cases be necessary to add, they can be in Minor SemVer releases, rather than Major SemVer.
