[Discover] User interactions telemetry for Discover

[rayafratkina]

Describe the feature:
In order to understand and improve Discover after rolling out the new EUI Data grid component, it will be helpful to see what actions user takes in the UI and what problems they encounter. Ideally, we should be able to connect individual actions performed within the same session.

Prior art: #46599

Describe a specific use case for the feature:

1. Overall

• User navigates to Discover
• User toggles the new UI switch on/off
• User adds a filter
• User changes time range
• User saves a searc
• User selects a saved search

2. Field list

• User looks at field information (value distribution)
• User adds a field
• User removes a field
• User clicks "visualize"
• User searches available fields
• User filters by type
• User adds a filter from the select field

3. Histogram

• User changes granularity
• User uses brush tool to select part of the time range

4. Table

• User expands a row
• User views json/table of expanded document
• User views surrounding documents
• User sorts by a column
• User removes a column

Could we get a shortened, prioritized version of the telemetry data @AlonaNadler ?

The questions im mostly interested to answer:

• What's the ratio between using data grid vs default log view - not sure what the best way to calculate it, especially since not all times users are saving it to a saved search.

• what users use more filters or search bar - maybe calculate the number of times a query is submitted from search bar vs filter is added

• count the number of times Visualize is clicked from the field list

The metrics have been added. We will add the actual metric to track how many times users have switched from the new EUIDataGrid to the legacy table once the PR is merged to master, no to pollute master with the metrics for the code that doesn't yet exist.

Sorry if it wasn't clear from the previous comment. The following metrics have been added:

• interaction with the filter / query bar, or more specifically:
  query_submitted: when a query is submitted from a search bar
  filter_added: when a filter is added from a filter bar
  filter_edited: when a filter is edited
  filter_invertInclusion: when filter results are included/excluded
  filter_toggleAllDisabled: when a filter is enabled/disabled
• discover:filter_added: adding filter from the document table
• discover:visualize_link_click: clicking Visualize button from the Discover field

Additionally, we have added support for tracking metrics in the Advanced Settings. We plan to leverage this to emit a metric for switching from EuiDataGrid to the legacy table, but the actual metric will be implemented once the EuiDataGrid PR is merged to master.

Closing this as the most requested metrics have been implemented and we currently don't plan on adding more unless required.
