Fix NoClassDefFoundError due to OSGI/servlet issues in IAST

[manuel-alvarez-alvarez]

What Does This Do

Separates call sites for javax.servlet.ServletRequest and javax.servlet.http.HttpServletRequest to prevent issues when classes are loaded in an OSGI environment.

Motivation

A customer reported an exception during initialization:

Caused by: java.lang.ClassNotFoundException: javax.servlet.ServletRequest not found by security-connector-oauth2-client [328]
	at org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation(BundleWiringImpl.java:1585)
	at org.apache.felix.framework.BundleWiringImpl.access$300(BundleWiringImpl.java:79)
	at org.apache.felix.framework.BundleWiringImpl$BundleClassLoader.loadClass(BundleWiringImpl.java:1970)
	at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522)
	... 78 more

The Apache Felix driven class loader of the instrumented class is only able to load classes in the javax.servlet.http package but the call site was forcing a reference to javax.servlet
