Improve webContainer metatype descriptions to include equivalent WebSphere traditional custom property names

[tkburroughs]

Many of the webContainer attribute descriptions already include the equivalent WebSphere traditional custom property names, however the following ones are missing. For several it is just exactly the same as the liberty attribute name, so perhaps it just needs to be clarified that if not otherwise specified, then it is the same?

This is the file to update:

• https://github.com/OpenLiberty/open-liberty/blob/integration/dev/com.ibm.ws.webcontainer/resources/OSGI-INF/l10n/metatype.properties

Liberty - webContainer attribute	tWAS - WebContainer Custom Property
allowExpressionFactoryPerApp	com.ibm.ws.jsp.allowExpressionFactoryPerApp
allowQueryParamWithNoEqual	com.ibm.ws.webcontainer.AllowQueryParamWithNoEqual
decodeUrlAsUtf8	DecodeUrlAsUTF8
directoryBrowsingEnabled	directoryBrowsingEnabled
fileServingEnabled	fileServingEnabled
httpsIndicatorHeader	httpsIndicatorHeader
listeners	listeners
serveServletsByClassnameEnabled	serveServletsByClassnameEnabled
stopAppStartUponListenerException	com.ibm.ws.webcontainer.stopappstartuponlistenerexception
throwExceptionWhenUnableToCompleteOrDispatch	com.ibm.ws.webcontainer.throwexceptionwhenunabletocompleteordispatch

And this one is documented, but seems to have a syntax problem in open liberty metatype description:

Liberty - webContainer attribute	tWAS - WebContainer Custom Property
metaInfResourcesCacheSize	com.ibm.ws.webcontainer.metainfresourcescachesize.name ?? extra "name" at the end

---

These are already documented in Liberty:
