v4.6.0

git_username authentication

We add an optional parameter git_username that can be set to authenticate in order to perform a scan.
While this parameter is not mandatory for GitHub (neither .com nor enterprise), it is needed for some private git servers and for private bitbucket repos.

If the git_token is not set, this parameter is ignored (since the tool cannot authenticate with a username without token).
On the contrary, if the git_token is set, the username used for authenticating the tool is either git_username (if set) or oauth2 (the default value, which is the one adopted by github)

The git_username parameter is supported not only in the python library but also in the CLI and in the UI (with a new optional input field).

Minor

• Fix dependencies for tensorflow
• Fix the double "category" input field in the UI (add_rule)
• Make the export_discoveries more efficient by not loading all the discoveries of a repo (unless needed)
