Remove Import-Package section from maven-bundle-plugin configuration

The maven-bundle-plugin can generate an appropriate Import-Package section in the OSGi manifest automatically. If an Import-Package section is present then it will override the default maven-bundle-plugin behavior.

As per rovarga - Import-Package is only ever needed if you consume a package which happens to have an '.impl' component in its name. As per OSGi, that implies implementation-level dependency and is discouraged. The fix is to use some creativity in naming your packages
