Update to remove mvn exec and use java -jar fatjar for examples (#227)
* 1. Added Spring boot maven plugin to create fat jar. 2. Created new main class as entry point for the fat jar. 3. Updated Readme and comments for all the examples * 1) Configured spring boot maven plugin to not include version in the generated fat jar name and updated readme and comments 2) Removed SpringBootApplication annotation from DaprMainApplication. 3) Minor formating changes * Update DaprMainApplication.java Co-authored-by: Artur Souza <artursouza.ms@outlook.com>
