Add more issue / pr creation params (#331)

adds assignees, labels, deadline, milestone params

- [x] add flags to `tea issue create` (this is BREAKING, `-b` moved to `-d` for consistency with pr create)
- [x] add interactive mode to `tea issue create`
- [x] add flags to `tea pr create`
- [x] add interactive mode to `tea pr create`

fixes #171, fixes #303
