Convert service dialog views and request detail view to Haml

As the first step of adding support for reconfiguring services,
the existing ERB views have been converted to Haml prior to
changing any logic.

Add read-only view of service dialog to request details view

Now approvers can see what options the user has selected to
assist in the manual approval process.

Add a reconfigurable attribute to service dialog fields

A user can now indicate which fields within a service dialog
can be modified during a service reconfiguration action. Any
fields that are not flagged as reconfigurable will be
read-only.

Create ServiceReconfigureRequest / Task model classes

In support of service reconfiguration, add request and
task classes to support the upcoming workflow.

Add support for service reconfigure

In support of PaaS-style use-cases where CFME services
are utilized to drive automation-driven provisioning, being
able to reconfigure an existing service with new parameters
is a requirement.  In support of this, services can now be
flagged as reconfigurable, which will give the user the
ability to modify the service parameters via the service
dialog.  Once submitted, the reconfiguration request will
use the existing approval process before invoking the assigned
custom automation to perform the reconfiguration steps.
