Service selection: Starting with labels besides service_name

[gtk-grafana]

Building on top of #801.
Fixes: #819

Allowing users to pick another label besides service_name on the service selection scene

Notes:

• Removing aggregated metrics from volume api calls
• Refactoring code "service" related, to use primaryLabel, primaryLabelValue instead
• Not renaming files yet to keep down on conflicts.

Somehow the label count in the tabs is not aligned to the values once a tab/label is selected:

I think we should rename this placeholder to Search values:

Can we remove the Loading services... copy?

I really like the feature, great job. Something that we discussed with @zizzpudding at one point was to add + buttons to label values next to the Select button. I think that would bring the biggest win here.
By using that + button, you can select a first set of labels/values at the starting page, and then click Select to navigate away from the "ServiceSelection" page.
I don't think that's something that necessarily need to go into this PR, but something that we should definitely iterate on.

This appears to be a discrepancy in counts between volume and detected_labels.

detected_labels:

Volume

Look at batch_kubernetes_io_job_name, detected_labels says cardinality is 3047, but we only get 100 results back from volume.

Is the above just that volume only returns results when the values are not empty?
Since the options were remove any cardinality counts from the tabs or deal with the discrepancy we opted to add a tooltip next to the logs volume count. We can revisit this if it turns out to be confusing or distracting to users.

Just a few nits, but overall LGTM!
