Make `UpdateRequiredITKVersionInFiles.sh` fetch files automatically

[jhlegarreta]

Description

UpdateRequiredITKVersionInRemoteModules.sh requires the remotes setup.py and azure-pipelines.yml files as input arguments. Making the script fetch those files automatically would be desirable.

Impact analysis

This would allow for a more efficient use of the script, a wider adoption of the script, and would allow to save time.

Expected behavior

Make the script fetch the setup.py and azure-pipelines.yml files automatically given the remote module name.

This would assume that both files are always at the same location (which is not the case currently for the former - rather than considering multiple paths, they should be made dwell in the same location according to the ITKModuleTemplate guidelines).

Actual behavior

The path to the setup.py and azure-pipelines.yml has to be provided to the script.

Versions

master.

Environment

Any.

Additional Information

Some inspiration could be taken from here (especially concerning the part of configuring, cloning, and looping over the remotes):

ITK/Utilities/Maintenance/UpdateRemoteModules.sh

Line 25 in 8fdb454

remote_modules_path=$(cd ../../Modules/Remote && pwd)

Since this issue was created, we have switched to GitHub actions, so there is no more azure-pipelines.yml. Now we have .github/workflows/build-test-package.yml.

Much work has been done that makes some of this issue no longer relevant.
