[MRESOURCES-274] set overwrite per resource

I have this StackOverflow question https://stackoverflow.com/q/65892723/206466
The problem is caused not by maven resources but by IntelliJ that's documented here https://youtrack.jetbrains.com/issue/IDEABKL-6745

Currently I am doing this workaround with `maven-resources-plugin`.

```xml

maven-resources-plugin


copy-resources
process-test-resources

copy-resources




true
${main.basedir}/configuration/runtime/default
${pom.basedir}/target/classes

saml.properties
dex-*-metadata.xml

false


${pom.basedir}/target
false



copy-resources
process-test-resources

copy-resources


false


false
${h2.db.dir}

dex_dev_unittest.mv.db



${pom.basedir}/target
false

```

but it would be nice if you could simply do

```xml

false

```

Start by locating the maven-resources-plugin implementation of the copy-resources goal and any tests covering resource configuration. Trace how the global overwrite setting is handled, then determine how a resource-level overwrite value should take precedence. Done means the XML resource setting supports overwrite independently for each resource and tests cover both true and false cases.
