Issue:
* There was no caching policy specified.
* -> Browsers use their own default policy.
* -> After upgrade, some Web UI files might have been actualized some not.
* -> With schema change may result into weird bugs in Web UI
Solution considerations:
1. Detect server version change and hard-reload at runtime
Detection is easy. Problem is the reload. Obvious candidate 'window.location.reload(true)' works in Firefox but not in Chrome because expected behavior when parameter is used is not in standard and therefore Chromium/WebKit authors did not implement it.
2. Application Cache
HTML 5 technology which lets web apps to run offline. Besides weird issues with event handlers which I encountered, this would be an ideal candidate. Simple change of manifest file would lead to reload of all files (requires reload of page to used the new files).
Showstopper was usage with untrusted certificate. If user did not add exception for the cert or its CA and would visit the page for a second time, all AJAX calls would fail.
3. Set Expires to now() for everything
Web UI rarely changes so this is an overkill. Setting it to different value is not a solution either. We can't predict when the upgrade will happen and when new Web UI will be needed.
Solution:
* Implemented a mini loader which loads basic resources. Dojo loader takes action after Dojo is loaded.
* The loader adds a version parameter (?v=__NUM_VERSION__) to all requests.
* Version is defined in the loader. It's set to current in `make version-update`.
* All static pages use this loader to fetch their resources.
* Version is also passed to dojo loader as cache-bust for the same effect.
* Expire header was set to 'access time plus 1 year' for /ui folder. Exceptions are HTML files and loader (set to immediate expiration).
Possible issues:
* Images are cached but not requested with version param.
* Images with version and without are considered different
* -> We would have to attach version to all URIs - in CSS and in JS. But we should avoid changing jQuery UI CSS.
* Proposed solution is to change image name when changing image. Image change is done rarely.
* Version is set by build and therefore updated just on server update. It might cause trouble with different update schedule of plugins.
* No action taken to address this issue yet.
* We might leave it on plugin devs (own .conf in /etc/httpd/conf.d/)
* or set expires to now for all plugins
* running `make version-update` is required in order to use static version of UI for testing

Map type radio used old way of defining that its value should not be used in add command. Recent patch related to 'enable' attribute hardened/fixed the behavior of radio widgets so they are disabled in UI as well when enabled==false. Automount did not reflect this change.

Old host entries are missing object class with krbticketflags attribute. Therefore UI does not receive attrlevelrights for it. This OC is added when ipakrbokasdelegate is set.
This patch adds the usual hack for such cases.

This action calls cert-request command which is not available on CA-less installs. Thus this action won't be enabled and therefore there is no reason to keep it visible.

Drops the code from ipa-server-install, ipa-dns-install and the
BindInstance itself. Also changed ipa-upgradeconfig script so
that it does not set zone_refresh to 0 on upgrades, as the option
is deprecated.

This patch optimizes options used in commands executed by search pages.
1) Removed --all from _find and _show commands used by search pages. All displayed attributes should be already included in default attributes.
2) Removed search_all_attributes - Not needed since introduction of paging.
3) Added --no-members options to search _show commmands. Members are not displayed on search pages and such change drastically improves performance. It reduces computations on server and amount of data transferred to Web UI.

Host and DNS adder dialogs used span element as container for block elements. It's not valid nor consistent with other forms.
'span' was replaced by 'div'

1. add class to active facet instead of using direct style modification for hiding/showing
2. add name attribute to tables and dialog buttons and error dialog
https://fedorahosted.org/freeipa/ticket/3744
There is a JS error.
Rule tables with external member has more than one column and therefore exclude parameter for adder dialog is not array of strings but array of objects. normalize_values function can't work with it and causes JS error.
This patch creates proper exclude array before passing it to adder dialog.

Facet pre_ops defined in ./facet module were moved to modules where facet are actually defined. Moved pre_ops were united with the ones defined for the facets in these modules.
The move simplifies module dependencies - there is no reason to have general facet module dependent on specialized facet modules.
Pre_ops uniting makes the code simpler.

Spec modifications in factories makes inheritance and extensibility more difficult.
Moving them to pre_ops allows modification of their output by other pre_ops.

Prompt for nameserver IP address in interactive mode of dnszone-add.
Add a corresponding field to dnszone creation dialog in the web UI.
This parameter is required if and only if:
* New zone is a forward zone
* Nameserver is defined inside the new zone
Add a new unit test to cover this functionality.

Introduce new command, 'trust-resolve', to aid resolving SIDs to names
in the Web UI.
The command uses new SSSD interface, nss_idmap, to resolve actual SIDs.
SSSD caches resolved data so that future requests to resolve same SIDs
are returned from a memory cache.
Web UI code is using Dojo/Deferred to deliver result of SID resolution
out of band. Once resolved names are available, they replace SID values.
Since Web UI only shows ~20 records per page, up to 20 SIDs are resolved
at the same time. They all sent within the single request to the server.
