What does this implement/fix? Explain your changes.

Improve expandEnvVariablesWithDefaults func in order to being able take default values strings that contains ':' (colon) and ',' (comma) symbols. In my case I need to add to default value host addresses in format like host1:3333,host1:2222,host3,4477
