[ddl-eric-jin]

Link to JIRA

DOM-59086

What issue does this pull request solve?

Uploading files to a Dataset on a windows can fail since the upload API expects a Unix-style filepath. The backslash will be interpreted as an escape character.

What is the solution?

When running python-domino on windows, transform the path to a Unix-style path, which the API to send an upload chunk for Datasets expects.

Testing

Tested domino.datasets_upload_files for a file located at "\test\test.txt" and added unit tests.

interesting - i’d have assumed that os.path.relpath would use os.path under the hood. but LGTM!
