Add support for 'scope' attribute to EventsApi #759
Description
An attribute was added around 2019 to the GitLab Events API for allowing the retrieval of all events for a user across all of their projects. This is the scope attribute, as listed here: https://docs.gitlab.com/ee/api/events.html#list-currently-authenticated-users-events
The EventsApi in gitlab4j-api currently does not have support for this attribute. I have a use case where I need to use this attribute to retrieve all events across a user's projects and would like to see this added.
I have made the changes in my fork and will be creating a PR shortly.
