METRON-1134: Allow parser command line options to be specified in the
zookeeper parser config.
## Contributor Comments
It would be useful to maintain sensible defaults for various properties in
the construction of parser topologies within the sensor parser config in
zookeeper. This, along with a UI, would allow people to manage defaults per
sensor in a single place. CLI should take precedent and override anything
stored in zookeeper.
Manual testing via fulldev should focus on ensuring the following
conditions hold for the properties able to be specified in the config:
* Specify the property in the config.
* Start parser and ensure that the property is preserved.
* Specify the property via the CLI param
* Start parser and ensure that the CLI param is honored
The properties able to be specified in the config are as follows:
* `spoutParallelism` : The kafka spout parallelism (default to `1`). This
can be overridden on the command line.
* `spoutNumTasks` : The number of tasks for the spout (default to `1`).
This can be overridden on the command line.
* `parserParallelism` : The parser bolt parallelism (default to `1`). This
can be overridden on the command line.
* `parserNumTasks` : The number of tasks for the parser bolt (default to
`1`). This can be overridden on the command line.
* `errorWriterParallelism` : The error writer bolt parallelism (default to
`1`). This can be overridden on the command line.
* `errorWriterNumTasks` : The number of tasks for the error writer bolt
(default to `1`). This can be overridden on the command line.
* `spoutConfig` : A map representing a custom spout config. This can be
overridden on the command line.
* `securityProtocol` : The security protocol to use for reading from kafka.
This can be overridden on the command line and also specified in the spout
config via the `security.protocol` key. If both are specified, then they are
merged and the CLI will take precedence.
* `stormConfig` : The storm config to use. This can be overridden on the
command line. If both are specified, they are merged with CLI properties
taking precedence.
