MLFlowClient v0.5.1

Diff since v0.4.7

• Moved baseuri to apiroot, allowing users to specify its own API route (improving compatibility with platforms)
• Removed healthcheck function due to lack of support. It is not working on every platform providing a mlflow instance
• Added a MLFLOW_TRACKING_URI check when running tests
