Setting useDefaultRepo=false in ${wlp.install.dir}/etc/repositories.properties ensures featureUtility does not install from Maven Central

The following behavior needs to be added in accordance to these 2 issues:

• featureUtility doesn't output error message for an invalid repo open-liberty#14162
• featureUtility tool using Maven Central if other custom repositories are failing is not correct open-liberty#30585

You can set the following in ${wlp.install.dir}/etc/repositories.properties:

useDefaultRepository=false

and with the following invalid liberty repo in ${wlp.install.dir}/etc/featureUtility.properties:

myRepo.url=http://alt.mycomp.com/maven2

the output will be something similar:

> featureUtility install mpHealth-2.2
Initializing ...
Using 8 threads to download artifacts.
