#959 Add dataproxy client selector Pull request opened by katrogan NOT TO BE MERGED UNTIL BE CHANGES ARE IN. This PR adds a new dependency on the flyte remote client for dataproxy endpoints 1. Use a client conn cache for dataproxy operations, using 'operation' and 'resource' as cache keys 2. On cache misses call SelectCluster to get the respective cluster endpoint and initialize and cache a new client conn Going forward all new dataproxy calls should use this pattern. Today this PR updates the only uses of dataproxy in the sdk: UploadInputs and CreateUploadLocation --- Testing Verified that the CreateRun path (which calls UploadInputs now) works with a local cluster
