[1100300] Update of a resource configuration sometimes takes more then 100 seconds
Initial commit for this.  Try to chunk work such that we don't perfrom
complete scans at large intervals, but smaller, partial scans at
more frequent  intervals.
- Add two new agent config props to assist in configuring the process.
JBossAS7: export "Domain Name" as a trait

We need this in order to have dynagroup definitions composed from Domain
Name + some other configuration property. Also, this property is called
'name' on HC, but in RHQ we call it 'domain-name' - this is because
dynagroup evaluator is not strict when it comes to trait names - so having
resource.trait[name] includes several traits.
[BZ 1099854] [BZ 1097698]- [as7] Incorrect expression in pre-defined

Provided expressions fixed - now taking into account domain-name trait.

Managed Servers in domain : now generates groups per domain-name = set of
all managed servers on all hostrcontrollers grouped by domain-name

Managed Servers in server-group: now generates sets grouped by domain-name
and server-group name.

I also fixed provided expression called 'Deployments in server-group' -
which was relying on Deployment resources under server-groups (recently
removed)
Introducing API checking to agent-server comms.
[BZ 1096902] - "Maximum" and "Minimum" values do not match the graph values - fixing a race condition in CustomDateRangeState
[BZ 1082806] - Context referrals are hardcoded to ignore in LDAP configuration - making sure the dbupgrade won't fail if the value is already present in the DB
[1110277] RHQ_EVENT table's detail field limit of 4000 character will break when a log message contains multibyte characters (UTF-8)
This is a problem in a few places, not just events.  We're not
properly protecting against the 4000 byte limit on oracle, just
the 4000 character limit declared on the varchar2 field.
- Add DatabaseType.getString() which can truncate as needed in
  a vendor-specific way.
- Use the new getString() to store safe versions of event detail,
  alert notification log message, and calltime dataset destination.
Bug 1098092 - It's not possible to query pre-defined dynagroup definitions
via CLI

Added boolean filter parameter to ResourceGroupDefinitionCriteria class - so
group definitions can be filtered for "userDefinedOnly" - which excludes
provided canned expressions.
Bug 1109272 - [as7] Incorrect description of ManagedServerDeployment
[1100300] Update of a resource configuration sometimes takes more then 100 seconds
Given feedback from the github pull request (62), change things around
to support tighter time controls at the expense of some more memory and
complexity.
- remove the 750ms delay between checks. This was supposed to be removed in
  the first pass of changes. Slows things down in a major way, the chunking
  should keep runtime spikes in check.
- increase check frequency to every 2 minutes but drop to 10s limit on
  runtime.  Now that the 750ms delay is gone, I ran a check of the 3 RHQ
  roots (EAP server, agent, storage) in well under 3s.  The time a
  root and its members are again eligible for a check is still 1 hour
  from the time it completes it's prior check (meaning it's last child
  is checked).

TODO: Still have to update logging to DEBUG once everything else is
      cleared.

[BZ 1070431] Provide initial CSP integration for opening JON cases

Added new WAR deployment containing RHA frontend and JON-specific backend
servlet
Integrate link to RH Access as a "Red Hat Support" button in main bar. For
testing purposes this view is accessible even for RHQ
add regular bootstrap fonts (required by RHA frontend angular stuff)
fix font paths in patternfly.min.css
[BZ 1070431] Provide initial CSP integration for opening JON cases

Added new maven profile called 'enable-rha' - enabled by default *only* in
release.sh when "enterprise" build runs, but temporarily enabled by for now.
This profile enables build and packaging of rh-access-war
move RH Access views from Help to standalone view, follow recommendations in
RH Acess menu layout
Added proxy server settings to system settings

this will need a change in jboss-software server plugin, which also has
proxy server settings. Plugin will fallback to server settings.
[BZ 1070437] (JON3-12) Provide initial CSP integration for opening managed
EAP cases

Added initial support in rh-access-war backend
read proxy server settings from global RHQ Server configuration
[BZ 1070437] (JON3-12) Provide initial CSP integration for opening ma

Implement "Open Support Case" menu item for Host Controller and Managed
Server and Standalone AS7 resources. In case of HC, RHA backend will provide
options to attach JDR reports from all it's managed servers.
AttachementServlet also now implements security - verifies sessionID sent in
http headers. Server JDR report options will be unchecked when server is not
UP (such report will fail to attach)
