Issue: SPR-11142

The observed behavior was that the client does not get a response from
the WebSocket HTTP handshake. On the server the handshake actually
succeeds, the response is set correctly to status 101, and the
WebSocketHandler gets notified of the successfully established
connection.

This change flushes the ServletResponse just before returning from the
GlassfishRequestUpgradeStrategy. This is actually what Glassfish's own
TyrusServletFilter does as well at the end along with a comment that it
is a possible bug.

Fix QuartzSupportTests that has been failing since the HSQLDB upgrade.

Attempt to improve performance by caching TypeDescriptors against bean

(cherry picked from commit 6ce2eb96)

Use AnnotationTransactionAttributeSource class name to avoid hard dependency on transaction.annotation package

Merged web.socket.messaging.config into web.socket.config and introduced web.socket.config.annotation

Fix ResolvableType.hashCode() to use the source of the variable
resolver, rather than the resolver itself.

Update "enableMatrixVariables" and "ignoreDefaultModelOnRedirect" to
use the more conventional XML form "enable-matrix-variables" and
"ignore-default-model-on-redirect".

Both forms are now supported by `AnnotationDrivenBeanDefinitionParser`,
with newer names being defined in the 4.0 XSD and the older names
remaining in the 3.2 XSD.
