We added the option to set the following env JFROG_CLI_UPLOAD_EMPTY_ARCHIVE for the following scenario:

1. JFrog CLI upload command
2. The --archive flag is set
3. The --exclusion is set and all files are being excluded by the exclusion pattern

The default behavior is to upload nothing.
The behavior with the new env it to upload an empty archive.

depends on jfrog/jfrog-cli-core#1124 and jfrog/jfrog-client-go#899
