support template for executions / profiles

[laeubi]

In the "old" maven editor there was a quite handy feature id like to call a "code template" here, it worked as follows:

Assume I have an XMl like this:

<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<modelVersion>4.0.0</modelVersion>
	
	<profiles>
		_cursor here_
	</profiles>
</project>

now I activate code completion (STRG+SPACE by default) there was a suggestion to add a new profile where one can stepp through the basic items like this:

<profiles>
	<profile>
		<id>_cursor_now_here</id>
		
	</profile>
</profiles>

the same (and even much more useful) was for executions where one usually needs, an id, a phase a goal .... to bind the execution.
