This is a proposed solution for US-613462 and pegasystems/pega-helm-charts#577 which allows a user of the pega Helm chart to define an env variable WEB_XML_SNIPPET which will be inserted into the web.xml just before the tag. This allows users to:
Add an additional servlet
Add a security constraint
Add JMS resources
Without the snippet feature, the user needs to either embed an entire 1600+ line web.xml into their values file, or put a replacement web.xml into the config/deploy folder (which either means using local charts instead of hosting in a repository, or having to repackage every chart release with the customization).
This feature also pairs with the existing functionality we have for specifying a CONTEXT_XML_SNIPPET.
