This reverts commit 331a26a4.

Fixes gh-4464

Allow `META-INF/spring-devtools.properties` files to be used by
application developers to declare is specific jars should be included
or excluded from the RestartClassLoader.

A typical example where this might be used is a company that develops
it's own set of internal JARs that are used by developers but not
usually imported into their IDE.
