Integration tests passed on local on latest durabletask-sidecar.
Added two integration tests, one is testing suspend instance, one is testing suspend and resume instance. Please let me know if they are sufficient. Thank you.

kaibocai (@kaibocai) great! So the next step for me is to update the sidecar container used by the CI. Can you also open an issue that tracks updating this documentation? https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-instance-management?tabs=java#suspend-and-resume-instances-preview

Hi Chris Gillum (@cgillum) , I have updated the unit tests (combine redundant tests and add one for testing termination). I found an issue in sidecar for method waitForInstanceCompletion, I raised a PR at https://github.com/microsoft/durabletask-sidecar/pull/19 can you take a look? Thank you.

[Chris Gillum (cgillum)]

Looks good! Just a couple small suggestions before merging.

[kaibocai (kaibocai)]

Updated the sidecar, all tests pass. Merging this PR!

1. Can we also have a ticket to return the HTTP endpoints for suspend and resume in the HTTP Response we get after submitting an orchestrator?
2. Also, the documentation is still not complete here : https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-instance-management?tabs=java#suspend-and-resume-instances-preview
