WFLY-2709 add missing resource key

The connector subsystem is missing the resource key
“connection-definitions.clear-statistics”. This results in a exception
when looking at the connection definitions of a resource adapter in
VisualVM.

 * add the resource key "connection-definitions.clear-statistics"

WFLY-2502 Naming context read-only during RA stop

When the ResourceAdapter#stop() method is invoked on an annotation
based 1.6 JCR resource adapter the naming context is read only. The
method can be invoked in two cases. Either a normal undeployment or
a clean up after a failed deployment.

 - AbstractResourceAdapterDeploymentService#stopAsync pushes the owner
 - AbstractResourceAdapterDeploymentService#unregisterAll catches any
   error that ResourceAdapter#stop may throw and logs it
 - AbstractResourceAdapterDeploymentService#cleanupStartAsync also
   pushes the owner
 - fix an unused import
 - convert various tabs to spaces
 - remove various trailing spaces

WFLY-2693 list-active-jsf-impls missing reply type

The DMR operation "list-active-jsf-impls" of the JSF subsystem is
missing a reply type. Therefore the operation will show up as "Void"
in VisualVM and no result will be displayed.

 * set the reply type to list
 * set the reply value type to string
 * replace #withFlags with #setRuntimeOnly and #setReadOnly
