No way to list all open issues in a project?

As a team manager, I need to interact with issues other than just mine. It doesn't seem there is a way to list all open issues. Even better (for me at least) would be a way to list all issues in the current sprint (or all completed issues, all inreview issues, etc)

**Describe the solution you'd like**
A few ideas:
`jirax list --all `
`jirax list --mine ` (default if no flags given)
`jirax list --user `
`jirax sprint --all `
`jirax sprint --mine ` (default if no flags given)
`jirax sprint --user `
`jirax completed --sprint ` (same as `jirax completed --sprint --mine`)
`jirax completed --mine `
`jirax completed --user `
`jirax completed --sprint --mine `
`jirax completed --sprint --user `

**Describe alternatives you've considered**
none that I can think of (other than just using the normal JIRA web interface)

Start by locating the existing jirax list, sprint, and completed command entry points and how they currently select the user's issues. Compare those commands with the requested --all, --mine, and --user examples, then verify the desired filters against the Jira REST API; done means the supported commands return the requested issue sets consistently.
