METRON-190: Make start_parser_topology.sh more adaptable regarding storm
topology configuration
Add the ability to specify the message timeout, the max task parallelism,
the number of ackers, the number of workers. Also allow the user to pass in
JSON file containing a map of extra storm configs.
I added the following extra options to `start_parser_topology.sh`:
```
-e,--extra_options <JSON_FILE> Extra options in the form of a
JSON file with a map for
content.
-mt,--message_timeout <TIMEOUT_IN_SECS> Message Timeout in Seconds
-mtp,--max_task_parallelism <MAX_TASK> Max task parallelism
-na,--num_ackers <NUM_ACKERS> Number of Ackers
-nw,--num_workers <NUM_WORKERS> Number of Workers
```
For instance, if you wanted to set some storm property on
the config called `topology.ticks.tuple.freq.secs` to 1000 and
`storm.local.dir` to `/opt/my/path`
you could create a file called `custom_config.json` containing
```
{
"topology.ticks.tuple.freq.secs" : 1000,
"storm.local.dir" : "/opt/my/path"
}
```
and pass `--extra_options custom_config.json` to `start_parser_topology.sh`.
