Enable CloudHub logging configuration when deploying applications

[jgalati-mulesoft]

• Added logLevels field to API call when deploying to CloudHub
• Added the optional property logLevelInfos to the CloudHub Deployment Maven Plugin

This PR makes it possible to add a logging configuration, while deploying an application to CloudHub 1 using the Mule Maven Plugin.

The mule-maven-plugin in a project's pom.xml should be configured as follows:

<build>
...
			<plugin>
				<groupId>org.mule.tools.maven</groupId>
				<artifactId>mule-maven-plugin</artifactId>
				<version>${mule.maven.plugin.version}</version>
				<extensions>true</extensions>
				<configuration>
					...
					<cloudHubDeployment>
                                          ...
						<logLevelInfos>
							<logLevelInfo>
								<packageName>com.muley.test.1</packageName>
								<level>DEBUG</level>
							</logLevelInfo>
							<logLevelInfo>
								<packageName>com.muley.test.2</packageName>
								<level>INFO</level>
							  </logLevelInfo>
						</logLevelInfos>
                                          ...
					</cloudHubDeployment>
				</configuration>
			</plugin>
...
</build>
