Get rid of axios dependency in the platform deployment management tests.

[azasypkin]

Summary

In #111655 (comment) we're trying to upgrade axios package, but are blocked because of the following axios usage in the tests (axios just happened to have methods signature similar to HttpSetup, but it's technically incorrect and quite fragile):

🚫 const httpSetup = axios.create({ adapter: axiosXhrAdapter }) as unknown as HttpSetup; 🚫

The path forward is to switch tests to use HttpSetup mock instead of axios + sinon server mock. There is an example and reference implementation in the Upgrade Assistant tests, see this pull request.

If you have any questions or don't have enough capacity to update the tests, please ping me and I'll try to help out.

Here is the list of the plugins that need to be updated (if I didn't miss anything):

• x-pack/plugins/cross_cluster_replication [CCR] Remove axios dependency in tests #128148
• x-pack/plugins/index_lifecycle_management [ILM] Remove axios dependency in tests #129009
• x-pack/plugins/index_management [IM] Remove axios dependency in tests #128171
• x-pack/plugins/ingest_pipelines [Ingest Pipelines] Remove axios dependency in tests #128467
• x-pack/plugins/remote_clusters [Remote Clusters] Remove axios dependency in tests #128590
• x-pack/plugins/snapshot_restore [Snapshot & Restore] Remove axios dependency in tests #128614
• x-pack/plugins/watcher [Watcher] Remove axios dependency in tests #128765

IMPORTANT: we have to backport axios upgrade to 7.17.x and hence updated tests should be backported to the 7.17 branch as well.

Thanks a lot, @sabarasaba! It looks like all tests in Kibana are green with the latest axios version 🎉
