feat(cmd/run): property configuration refactoring

[squakez]

With this PR we finalize the refactoring of build and runtime configuration properties as described in #2003 :

• build-property file support (ie kamel run --build-property file:conf.properties ...)
• new property file format as build-property (ie kamel run --property file:conf.properties ...)
• deprecation of --property-file in favor of --property file:conf.properties
• modeline support for --property and --build-property flag
• E2E test for all the supported properties file flags
• Full set of examples for all properties flags (also with modeline enabled)

The original issue was mentioning the creation of a --config-property flag. However, I think it's better to keep the usage of --property which is already widely used and quite meaningful among developers.
