Merge multiple git-repos into one where each repo becomes a sub-directory

What it does

This script is hacket together to make merging multiple repos into one as easy as possible. It clones each sub-project and then uses git-filter-repo to move each repo into a sub directory. Finally it uses for the final merge.

In other words, it takes this:

| project-1 (separate repo)
| - dir-1
|   - file-1.txt
| -

External configuration in Grails 3

Working on Grails 3 I realized that I no longer can specify external configuration using the standard grails.config.locations property in Config.groovy file.

Reason is obvious! There is no Config.groovy now in Grails 3. Instead we now use application.yml to configure the properties. However, you can't specify the external configuration using this file too!

What the hack?

Now Grails 3 uses Spring's property source concept. To enable external config file to work we need to do something extra now.
