`import/get(-url)`: complete `--job` description

[shcheklein]

We should clearly define the logic behind defaults, e.g. like @isidentical mentioned we do the following for the import-url:

For import-url, it goes with --jobs => remote.jobs => core.jobs => BaseTree.JOBS

while what we mention (in import, get) is only remote modify jobs and BaseTree.JOBS (defaults). So, part about core.jobs is missing. Which might be important since it can be used to override the behavior globally for example.

Is it the same process for get, import-url, get-url? Maybe you can help us confirm @dberenbaum ? Thanks!
