Apply dynamic database configuration

Hard coded database configuration for Liquibase has been removed and
being replaced with place holder. Same implementation being applied
for application-dev.yml and application-prod.yml.

User can pass the parameters from maven build command. Example:

mvn clean package -Ddb.host=localhost -Ddb.port=5432 -Ddb.name=athena -Ddb.username=athena -Ddb.password=2948f5a3b9b3ca2d991c40c8d523bf07

Closes gh-1.
