[JIRA] (JENKINS-58544) Implement HTTP client retries

Issue Type:	Improvement
Assignee:	Lenin Raj Rajasekaran
Components:	atlassian-jira-software-cloud-plugin
Created:	2019-07-18 11:14
Priority:	Minor
Reporter:	Rafal Myslek

We should make sure the plugin does retries on ingestion when timeouts/errors happen.

We should add retries to the OkHttp client config we use in the plugin. It looks like OkHttp already does some retries out-of-the-box: https://medium.com/inloopx/okhttp-is-quietly-retrying-requests-is-your-api-ready-19489ef35ace

In these 3 scenarios, retries are handled automatically by Okhttp: https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/-builder/retry-on-connection-failure/

Based on the server response, we can also add additional logic to perform retries.

Implementation:

We can do 3 retries with a delay of 2 seconds between each try when we receive 5XX from the ingestion API.
