Add RSA key to Win2012R2 box

[hunner]

tl;dr the box should ship with an RSA host key instead of a DSA host key.

The 1.0.0 box version ships bitvise ssh server with the vagrant insecure ssh key (that is good) and a DSA host key (that is bad). From the OpenSSH docs:

OpenSSH 7.0 and greater similarly disable the ssh-dss (DSA) public key algorithm. It too is weak and we recommend against its use.

To get vagrant ssh to work I have to use the bitvise gui to generate an RSA host key, then click Employ to enable it.

Thanks for logging that!

It appears I missed that step in the 2012 box, I did go back and look at the 2003/2008 boxes and they do have that already set. My bad.

Hoping to ultimately packertize these boxes and rebuild them more often so the tools that are included stay more up to date.
