Remove MergePlugin

This is no longer used and we should favor shadow plugin instead.

/**
* Gradle plugin that allows projects to merged together. Primarily developed to
* allow Spring to support multiple incompatible versions of third-party
* dependencies (for example Hibernate v3 and v4).
* <p>
* The 'merge' extension should be used to define how projects are merged, for example:
* <pre class="code">
* configure(subprojects) {
* apply plugin: MergePlugin
* }
*
* project("myproject") {
* }
*
* project("myproject-extra") {
* merge.into = project("myproject")
* }
* </pre>
* <p>
* This plugin adds two new configurations:
* <ul>
* <li>merging - Contains the projects being merged into this project<li>
* <li>runtimeMerge - Contains all dependencies that are merge projects. These are used
* to allow an IDE to reference merge projects.</li>
* <ul>
