Support ant patters in coverage report property

Our workflow is as follow:

Unit test project include a target file that calls a nunit runner task, this task produces coverage and unit reports. Those are run when project compiles. The reports are created, 1 per assembly, using the name of the assembly.

The sonar analysis runs after this and picks the reports created by the build, the issue here is that we have many projects and every time more are added, we have strict rules on the inclusion of the target file since we need the tests to run after the build. However we do not required developers to add a new report into the properties file.

We this pr, we just specify *.coverage.xml and all xml reports are imported into sonar correctly and data is always consistent.

This was possible in the previous 2.1, so can this be considered from the next release?

Thanks
