Add crowbar-status and crowbar-failed in schema

Otherwise, barclamp_mgmt_lib.rb will edit the schema and add them, which
will make the files differ from the ones in the package.

Part of https://bugzilla.novell.com/show_bug.cgi?id=776583
Set proposal_schema_version to 2 in crowbar.yml

This is needed when we have crowbar-status/crowbar-failed in the schema.
parse_node_data: allow key elements containing '.', by backslash-escaping

    ./parse_node_data -a 'foo.2\.0.bar' test.json

will now return 'value' when fed:

    {
      "foo": {
        "2.0": {
          "bar": "value"
        }
      }
    }

This is now required since we will be enumerating repositories to be
included in autoyast.xml generation from meta-data contained in
provisioner.json, and we want to key that meta-data by repository
name to avoid requiring an extra set of repository keys.  Repository
names can be things like "SUSE-Cloud-2.0-Updates", hence the need for
allowing JSON key elements to contain ".".

There is a corresponding commit in the top-level crowbar repository
adding the same behaviour to json-edit.
add support for autoyast installation using external SMT server

Appropriate JSON would be something like:

    {
      "attributes": {
        "provisioner": {
          "suse": {
            "autoyast": {
              "repos": {
                "SLES11-SP3-Updates": {
                  "url": "http://smt.suse.de/repo/$RCE/SLES11-SP3-Updates/sle-11-x86_64/"
                },
                "SLES11-SP3-Pool": {
                  "url": "http://smt.suse.de/repo/$RCE/SLES11-SP3-Pool/sle-11-x86_64/"
                }
              }
            }
          }
        }
      }
    }
add support for ssh access during autoyast

Appropriate JSON would be something like:

    {
      "attributes": {
        "provisioner": {
          "suse": {
            "autoyast": {
              "ssh_password": "<password>"
            }
          }
        }
      }
    }
Use /var/log/crowbar/sledgehammer instead of /install-logs

Be a good citizen and put logs where they belong too.

Added support for filtering barclamps not supported on the OS being installed.
Any barclamp can define in crowbar.yml the parameter unsupported_os and if it
is defined, the roles corresponding to the barclamp will be removed on the nodes
where the target_platform matches.
