feat(sagemaker): Added the api path to the detached server for supporting reconnection

[msgupta-amazon]

Problem
Currently we don't support reconnection for parker.

Solution
This PR is the first step to add that functionality.
As part of this PR, we are just adding the route to the detached server for the api.

Testing
This feature will be released as independent components and this PR is for the first component, therefore we have made sure that there are no exiting functionalities breaking and we are able to call the api locally.

Note
Changelog won't be added as it is a component of the feature not the whole feature which is getting released.
Failures in the tests are unrelated to sagemaker service.
