Service SLI View w/ Dependency Tables

Describe the question you are looking to answer

When investigating a specific service, I want to understand the health of the services down-stream dependencies (databases) and up-stream dependencies (ingress, other services etc. )

Example scenario

A frequent debugging scenario is when a service's latency spikes when their database read writes spikes. For an SRE or SWE debugging, it's difficult to know whether the db is trashed because of their service or other issues.

Desired output

1. Service SLI Metrics Charts (latency, error-rate, rps)
2. Service-specific K8s metrics (CPU, Memory, IOPS etc. by pod)
3. Downstream Dependencies Summary Table ( SLI Metrics by dependency)
4. Upstream Dependencies Summary Table ( SLI Metrics by dependency)

Additional requirements

• We should be able to navigate too the dependencies own live view from the table
• Ideally, we would like to view the dependencies in a format that's easy to understand (eg: topological map)

Desired collaboration scheme

• Do you want to share this view with your team (yes/no)? Yes
• Do you want to persist this view in your team's git repo (yes/no)? Yes
• Do you want to persist this view in pixie-community's git repo (yes/no)? n/a

(Optional) Draft scripts
n/a
