Further comments

Note: first commit has all code, second commit has a bunch of snapshots in json format

Test failures:

• atlas,search_nodes: failing on master, depends on CLOUDP-308460 Failed Test: mongodb-atlas-cli-master-TestMain/atlas_search_nodes_e2e/e2e_atlas_clusters #3775
• atlas,generic: failing on master (flaky on evergreen, constant red on GA)

Excluded tests:

• atlas,clusters,flags: needs investigation on why it fails on snapshot mode
• atlas,interactive: needs investigation on why it fails on snapshot mode
• atlas,deployments,atlasclusters: one assertion connects to DB (needs live mode), if we keep this assertion it will never work on snapshot mode
• atlas,deployments,local,auth,deprecated: needs docker to run, we need to check if GA supports it
• atlas,deployments,local,auth,new: needs docker to run, we need to check if GA supports it
• atlas,deployments,local,nocli: needs docker to run, we need to check if GA supports it
• atlas,deployments,local,noauth: needs docker to run, we need to check if GA supports it

Follow ups:

• Remove tests from evergreen (deduplicate tests): not done, might be safer to monitor a couple of days first
• Open Jira tickets when tests fail: not done needs a followup PR
• Open Jira tickets when update job fails: not done needs a followup PR
• Integrate e2e snapshot tests coverage calculation: not done needs a followup PR
• Remove coverage from evergreen: depends on above item

Could you define these strings as constants?

[q] What's the reason for using a map[string]map[string]any{} over a type Memory struct that contains a strongly typed version of the memory?

[jeroenvervaeke]

Could you also turn this into a constant?
