Example for development flow - deploying a small code change of an MTA module in development

[ddonchev]

this example should feature initial environment configuration with 'cf deploy' & consequent app updates with cf push --no-manifest -p <path to built app bits>

Consider splitting this topic to multiple examples in which the build is orhcestrated:

• with mbt Showcase partial mbt module build+ mtad.yaml generation; partial deploy along with cf push;
• with standard tooling (maven/grunt/gradle/..) Showcase deploy from directory cf deploy ./ along with cf push
