When using S2I build and exec the command line and application properties fail

[donovanmuller]

When using an S2I build strategy with the exec entry point style, the following two tests fail:

• testCommandLineArgumentsPassing
• testApplicationPropertiesPassing

This is as a result of the command line args being converted to a JAVA_ARGS environment variable (as we cannot override the Docker Entrypoint with a S2I build) and the variables values not being properly escaped.

These tests need to pass by properly escaping the converted command line values.
