> Support quoted strings for environment variables

>             Project: Hadoop YARN
>          Issue Type: Bug

> There are cases where it is necessary to allow for quoted string literals within environment
variables values when passed via the yarn command line interface.
> For example, consider the follow environment variables for a MR map task.
> {{MODE=bar}}
> {{IMAGE_NAME=foo}}
> {{MOUNTS=/tmp/foo,/tmp/bar}}
> When running the MR job, these environment variables are supplied as a comma delimited
string.
> {{-Dmapreduce.map.env="MODE=bar,IMAGE_NAME=foo,MOUNTS=/tmp/foo,/tmp/bar"}}
> In this case, {{MOUNTS}} will be parsed and added to the task environment as {{MOUNTS=/tmp/foo}}.
Any attempts to quote the embedded comma separated value results in quote characters becoming
part of the value, and parsing still breaks down at the comma.
> This issue is to allow for quoting the comma separated value (escaped double or single
quote). This was mentioned on YARN-4595 and will impact YARN-5534 as well.
