Enhancement: Zeek Plugin support

[cplmayo]

Zeek supports multiple plugins that add additional functionality to the network monitor.

If this package could add support for searching and installing plugins via the Zeek package manager it would greatly enhance the utility for traffic monitoring.

I have manually installed Zeek via the FreeBSD ports and was able to manually add this functionality to a pfSense network appliance but management had to be done via the console vs the webgui.

Thanks for building and making this package available.

Echoing @cplmayo's comment, having zkg part of the package will indeed be a great addition.
