New Protocol NFS

[termanix]

Lately I've been thinking about what NetExec needs in development and I thought seeing NFS shares would also help with development.

It's using RPC and enumerating NFS Shares and if accessible, it finds files recursively.

Together with @Marshall-Hallenbeck, we were able to bring it to its current state (Thank you Marshall for helping). I hope it will be a useful protocol for everyone.

Here it is some screenshots:

My test lab,

192.168.37.130 : Server 2019 Domain Controller 192.168.37.131 : Ubuntu 6.8.0.-31

And also including UID brute force for if anonymously authentication fail.

Added ipv6 support to the NfsClient library as well as the protocol:

All flags and output works nice /w Neff

Actually we can query the uid needed for the share lol. Implemented an autodetecting feature that will automatically set the uid matching to the listed repository:

Download and upload files added.

To Do:

 - When uploaded a file, we cant read it. 
 - There are a few bugs on Windows while get-file, put-file

[NeffIsBack]

--get-file and --put-file are working as well 🚀 Escept for windows

[termanix]

To Do: Only left puf-file bug fixes for windows and linux.

[NeffIsBack]

Up&Download are working now against Linux&Windows. Also found the solution for setting file permissions 🎉 Default is 777 for now

@termanix if you can verify the behaviour on your side we should be good to go 🚀

[termanix]

@NeffIsBack On my side everything is fine now! It can be merge after your last review. 🚀
