Memory update (#379)

* Updated the memory usage of Tasks. Still in Progress.

* Merged Task and ServiceTask -> Currently not fully working!!!

* Fixed bugs that made the merger between Task and ServiceTask not work well.

* Updated jdk version for Dockerfile

* Removed ServiceFlavor.java and Task.kt
