I would like to open a conversion about adding support for remote MLFlow server.

User story: As a corporate employee, I'd like to be able to send MLFlow tracking information to our company server to have experiments across all teams in one place.

Feature needed: Adding basic auth or bearer token to the header of the HTTP requests.

1, Would you be interested in adding it? I'm happy to open a PR.
2, What would be the suggested implementation?

Re 2)
I would propose to:

• extend the MLFlow struct with an auth token in types.jl - add headers() method (similar to uri() method) that would set up the right headers for mlfget() and mlfpost() methods in utils.jl

What do you think?
