Review comment:
This code is way to confusing. It strikes me as very odd that `args` is
never null, and the naming scheme is weird (args should be "argsList",
"argsStr" should be "args" to be somewhat consistent with the method arguments).
I would pass in a single collection as arguments and a simple enum for how
arguments should be passed.

> Project: Flink
> Issue Type: Bug
> Components: REST, Webfrontend
> Affects Versions: 1.5.0, 1.6.0, 1.7.0
> Reporter: Gaurav Singhania
> Assignee: Andrey Zagrebin
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.7.0

> Attachments: sample_request.txt
>
>
> We were upgrading from Flink 1.4 to 1.6. At present we have a jar which takes
> all the details to run the job as program args against a jarid, including sql
> query and kafka details. In version 1.5 the program args are tokenised as a
> result single quote (') and double quote(") are stripped from the arguments.
> This results in malformed args.
> Attached a sample request for reference.
