Improve the possibility to overwrite services

[arobirosa]

Is your feature request related to a problem? Please describe.
I want to create a new implementation of the localizedImpexService and it is difficult to overwirte the bean and at the same time create a decorator.

Describe the solution you'd like
Beans without autowiring with bean aliases.

Describe alternatives you've considered
Duplicate the bean creation.

Additional context

[arobirosa]

The PropertyFileDeploymentScriptConfigurationReader and PropertyFileDeploymentScriptConfiguration must be more extension friendly. They currently have too many private methods which can have protected access.

[arobirosa]

I will only change the 3 named classes because it would be too risky to replace the autowiring by type with one by name. This change will surely break any project where the Areco Deployment Manager was customized.

Now those classes and the ArecoDeploymentScriptsRunner can be easily overwritten.
