Summary

Depending on the context the value for a place holder should be formatted differently. In Java for example classes, artifacts and packages have different cases. So support for something like REPLACE_ME_APP_NAME:CAPITAL_CAMEL_CASE to have the application name "my fine app" be inserted as MyFineApp would be handy.

In combination with #1839 and #1848 it would be handy if a directory named something like REPLACE_ME_GROUP:LOWER_CASE_SLASH_SEPARATED would be transformed to the directory hierarchy com/github/jenkinsx if REPLACE_ME_GROUP was set to com.github.jenkinsx.
