simulator: removing cyclic dependency from simulator

The database creator caused a cyclic dependecny in the simulator which
is removed with this commit. Additionally the simulator profile is now
merged with developer profile and a test for server health is included

Steps to run:
$ mvn -Pdeveloper clean install
$ mvn -Pdeveloper -pl developer -Ddeploydb
$ mvn -Pdeveloper -pl developer -Ddeploydb-simulator
$ mvn -pl client jetty:run

To deploy an adv. zone and test the server health:
$ mvn -Pdeveloper,marvin -Dmarvin.config=`find . -name simulator.cfg` -pl :cloud-marvin test

Conflicts:
	pom.xml

marvin logging: write to tmp to adjust for mac-osx

/var/log is not available on OSX. This breaks the simulator run.
CLOUDSTACK-1308 and CLOUDSTACK-807
run the test lifecycle only when config is specified
jvmArgs is invalid here

jvmArgs are unaffected in the jetty:run configuration. Use MAVEN_OPTS
for this instead.

remove dependence on dsl iso

No need to download the 50MB iso for every test. It is sufficient to use
a dummy iso. This dummy iso was generated using mkisofs for test
purposes.
