FreeBSD support

Hi Crowdsec community,

We would like to inform you about our progress for the FreeBSD Operating system support of crowdsec agent.

The upstream package is available and you could now install the agent using pkg(8):

sudo pkg update
sudo pkg install crowdsec

Current architecture target is amd64 but nothing should prevent you to build from ports on others architectures (i386, arm, etc.).

There are multiple things to take care about while running crowdsec on a non Linux-based platform and we are working to address them.

In the meantime, if you want to test and report anything feel free to use the following issue #651. At the moment, the agent configuration need to be deployed manually.

We are tracking FreeBSD support efforts with the following GitHub project.
