Publish module level root application context for web modules

[GoogleCodeExporter]

Applies as of r4677

Web framework integration often requires access to
WebApplicationContextUtils.getRootApplicationContext. 

This is accomplished by 
ImpalaServletUtils.publishRootModuleContext(servletContext, moduleName,
applicationContext)

However, this method needs to be called before context loading to make web
framework integration easier, and to be reversed if context loading fails
for that module.

Could be tied to modules of type 'web' by default.

Might be good to attempt to impose an ordering so that web framework servlets 
get
loaded last
