More default values and simplify onap config

Populate more default values for ansible all.yml configuration
to make it simpler by default for user.

Removed project_configuration variable as it caused just
confusion. Replaced that mostly by using app_name variable.

According to above changed simplified actual configuration
config/application_configuration.yml used to install onap.
Mostly removed repeation of comments.

Also updated ansible/application/README.md that was not
updated for a while.
