netutils Citrix NetScaler Parser

This PR is for adding a Citrix NetScaler parser. I've included an example for the unit test and confirmed tests are passing. Please let me know if there are any other tests I need to write for this. This should address one of the requests in #86.

Do you mind rebasing and running tests? You will have to run the development script in the root of the directory to regen one of the docs.

My branch has been rebased onto develop to pick up the documentation changes and I've run the development_scripts file and pushed the documentation update. Should be good to go now.

Also would be worthwhile based on the result of @itdependsnetworks comment above, if we don't want parent/child we should put a note similar to this for NetScaler. https://netutils.readthedocs.io/en/latest/dev/dev_config/#fortinet-fortios-parser

@jeffkala I've made a note in the documentation about the lack of parent/child relationships due to the configuration structure. I've also gone ahead and added the tests requested @itdependsnetworks.
