Cartridge application lifecycle

In a nutshell:

1. Create an application (for example, myapp) from a template:

   cartridge create --name myapp
   cd ./myapp
   

2. Build the application for local development and testing:

   cartridge build
   

3. Run instances locally:

   cartridge start
   cartridge stop
   

4. Pack the application into a distributable (like an RPM package):

   cartridge pack rpm
