Account for runners with multiple IP addresses

Default

When there are groups of runners, the runner managers may have different IP addresses. Today, we show the IP address of the runner manager that last contacted GitLab. This means that the IP address may change depending on which runner manager contacted most recently.

Proposal

• If there are multiple IP addresses across the runner managers, update the IP address field to be the first registered IP address followed by (+x) where x is the number of additional IP addresses belonging to the runner managers.
• If the IP address is the same across the runner managers, show the IP address in the list.
• Designs in design management
• Figma
