[SLO] Make SLO instance ID selectable/copyable

[jasonrhodes]

The SLO instance ID is currently not easily selected or copied from the UI, but users want the ability to grab this value for further investigation.

From @rdnm:

a lot of the time I want to grab the project ID to check it still exists. We see a lot of violated SLOs where the project just doesn't exist any more

From @pmoust:

I should be able to select the value of the key used as instanceId of an SLO that is using the group_by feature. In this case I am not able to select the uid of the proejct in the "handling_project:" seen in the screenshot (MacOSX / Chrome)

@kdelemme EUI provides a utility for this that might help you out here and make the ability to copy more discoverable (i.e. as a distinct button alongside the badge).

@ryankeairns Yes I've been using it elsewhere :) I'll cook something quickly when I'm done with my current work

I guess we can close @jasonrhodes
