[Vis Augmenter / Feature Anywhere] Add test suite for vanilla OSD + helper fns for plugins

[ohltyler]

Description

Using draft PR #683 as a jumpstart in this PR

Adding initial tests for augment-vis / feature-anywhere feature. The added test suite here is mostly regression testing to ensure a variety of visualization types render as expected on a dashboard, and the new feature doesn't break anything. It is intended to only be run as part of core/vanilla OSD, since we expect dashboards to behave differently when the onboarded plugins (AD/Alerting) are part of the cluster (e.g., 'Anomaly Detection'/'Alerting' options show up as options under eligible visualizations on a dashboard).

Primarily focusing on helper functions that can be consumed by the downstream plugins to bootstrap their test cluster environments. This includes:

• ingesting sample data (can be modified to fit plugin use-cases later)
• creating a visualization with configured metrics
• creating a dashboard
• creating a single function to do everything (ingest data, create dashboard, create visualizations). this way, plugins can use this and then immediately add on their actions to start testing, such as navigating to the respective plugin's option under an eligible visualization's context menu to begin creating anomaly detectors / monitors
