Do not select Swift proxy node as storage node

When one node had a controller role set, it was
select as storage node as well. Skip it, to preserve
behavior of non-role layout.
Add optional crowbar-applied boolean attribute to schema

We add a crowbar applied attribute to mark the proposal as applied after
the chef run. This allows the UI to show that the current form of the
proposal has been 'applied' successfully (i.e. chef-client completed the
run w/ success) and that the proposal was not modified after that.

Update the proposal_schema_revision, so we can add the attribute to
schema for ('3rd party') barclamps that currently do not have it.

Refs: crowbar/crowbar#2044 (which adds this attribute to barclamps which
lack it), crowbar/barclamp-crowbar#1068 (which marks the proposals as
applied) and https://bugzilla.novell.com/show_bug.cgi?id=877486

Update config template files to Icehouse

The most important change is in the middleware pipeline for the proxy:
  - gatekeeper, container_sync and dlo are added:
    - gatekeeper got added to filter headers.
    - container_sync is a new middleware related to configuration of
      container sync. We could add a config file for container_sync
      (container-sync-realms.conf) but we didn't have any config for
      that before, so we should be fine.
    - dlo simply got split (like slo before)
  - tempurl is moved before slo and dlo, as suggested by the doc.
