Description of PR

Enable asynchronous scheduling by default for capacity scheduler.

This commit enables asynchronous scheduling by changing the config default value to true. Additionally the commit also adds documentation changes for different scheduling strategies.

Note: Although asynchronous scheduling is enabled by default, for unit testing disabling it by default to give more control over container scheduling while simulating complex tests (i.e synchronous scheduling gives more control over when to schedule the container for simulating certain cases while writing unit test).

How was this patch tested?

Existing Unit Tests

For code changes:

  • Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
  • Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
  • If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
  • If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
