leap_cli: create dev.bitmask.net cert + key
right now, "leap cert update" only updated/creates production certs. in bitmask, we have the workaround to symlink the dev certs to the production ones:
ls -la files/cert/dev.bitmask.net.crt lrwxrwxrwx 1 varac varac 15 Sep 24 22:13 files/cert/dev.bitmask.net.crt -> bitmask.net.crt
but the browser will complain about a CN of bitmask.net when you go to https://dev.bitmask.net/ (firefox won't let me connect at all)
