Import the config bucket and put installed version file there. (#473)

1) We reference the config bucket from a lot of the scripts and docs.
Hence
make sure we also create it here. Use terraform import cli, since we're
   still on a too old version for using the import statement.
2) create the crc version in the config bucket, as the setup-robot is
   conditional.
