The issue is that the task name needs to be 'post_deployment_start'

expected result:
API should return 4xx (404?) about unknown task name, client should catch this message and provide a useful message to the CLI caller

We have two bugs #1551902 and #1551904 with same complaints. Looks like the first one is about code and the second one is about docs.

[Bulat Gaifullin (bulat.gaifullin)]

in task-based deployment option --start and --end does not supported by nailgun. The feature custom-graph-execution[1] can be used to run any deployment graph.
We need to fix api handler of nailgun, it should return meaningful error instead of 500.
Also need to remove this options from fuel-client.
