Configurations with values contains space may cause TM failures on Yarn

Currently on Yarn setups, we are passing task executor specific configurations through dynamic properties in the starting command (see FLINK-13184).

If the value of configuration contains space, the dynamic properties may not be correctly parsed, which could cause task executor failures. On occurrence can be found in FLINK-15047.

It would be good to allow spaces when passing dynamic properties. E.g., surrounding the values with double quotation marks, or escaping special characters.
