I did not find any existing property that defines the
`PARSER_TOPOLOGY_OPTIONS` value. It is hard coded in one of the MPack Python
scripts (`parser_commands.py`) as `' -e ~' + self.__params.metron_user +
'/.storm/storm.config'`.
I thought that if I just put the exact value here, we are half way to
making it configurable in Ambari, if we choose to do so.
I also tried to use `~${METRON_HOME}/.storm/storm.config`, but the
`ProcessBuilder` does not do tilde expansion for user's home directories.

> Project: Metron
> Issue Type: Bug
> Reporter: Nick Allen
> Assignee: Nick Allen
>
> The Metron Management UI cannot start topologies in a kerberized environment.
> This includes the parser, indexing, and enrichment topologies.
> It seems that Metron REST does not pass "-ksp" to the start topology
> commands. As a result, topologies that are started with the Management UI
> cannot start a producer against a kerberized Kafka.
