All parameters should be optional

The following snippet should be enough to run utplsql :

<plugin>
                <groupId>${project.groupId}</groupId>
                <artifactId>utplsql-maven-plugin</artifactId>
                <version>${utplsql-maven-plugin-version}</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>test</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

Today it requires sources / tests and reporters tags which are not always necessary.

Path can/should be optional too as it defaults to all tests from current schema (connected user)
