Allow multiple packages to be defined with package_to_scan env var

[nehashri]

Current Behaviour
To optimize the classes scanned to find all steps, hooks etc, we have a environment variable called package_to_scan. This takes only one value right now.

Expected Behaviour
package_to_scan should take multiple values.

should be available in nightly >= 06-06-2018

just found this now - cannot find documentation about the variable - is there any ?

Does the variable accept packnames or also wildcards ? So would com.mydomain.* be valid and scan all subpackages of com.mydomain ?

@ajoecker It looks like this feature was implemented already. However there seems to be some issues related to this, they are referenced above.

The current implementation is that, package_to_scan environment variable can be specified, it can take a comma separated list of packages. If a package is specified, it should scan all its subpackages as well.
For example, package_to_scan = com.thoughtworks effectively returns URLs from the classpath containing packages starting with com.thoughtworks.
For now, we don't allow wildcards here.

then no wildcard is needed... thx @nehashri
