Allow workflow configuration in folders inside .github/workflows

Code to Cloud GitHub Actions
#1

Hi,
it would be nice to be able to create folders inside .github/workflows and have same structure on github actions web ui.

For example

.github
└── workflows
    ├── build
    │   └── build.yml
    └── tests
        ├── test1.yml
        └── test2.yml

With this structure i’ll have only few folders in github actions web and feel much more comfortable than with tons of workflows.

Regards,
Andrii
