Add option to remove "comments" from configs

[agember]

It would be useful to include a command-line option that removes "comments" from configs. For example, interface descriptions, BGP neighbor descriptions, remarks in ACLs, etc. Developing keyword lists for this is often non-trivial, so the ability to remove them outright, especially since they don't impact network semantics, would be useful.

Hi @agember,
I am collaborating with @Elviraant and I am interested in taking over this issue. Contributing to an open-source project is an assignment for "Software Engineering in Practice" offered by the Management Science and Technology department of AUEB. Could you assign me this issue?
Thank you,
Theodora

Hi @tandreadi, You'll need to ask @dhalperi to assign this issue to you, since I do not have administrative access to this repository. Also, you may want to look at the modifications in my fork of the repository, which are a first attempt at solving this problem: https://github.com/colgate-cs-research/netconan/tree/aaron-line-anonymization
I am happy to provide additional suggestions/guidance if you're interested; you can also find me (and other folks) on the Batfish Slack workspace: https://join.slack.com/t/batfish-org/shared_invite/enQtMzA0Nzg2OTAzNzQ1LTcyYzY3M2Q0NWUyYTRhYjdlM2IzYzRhZGU1NWFlNGU2MzlhNDY3OTJmMDIyMjQzYmRlNjhkMTRjNWIwNTUwNTQ
