Make 7.x like 6.7 user agent ecs, but default to true (#38828)
Browse files Browse the repository at this point in the history 
Forward port of #38757

This change reverts the initial 7.0 commits and replaces them
with the 6.7 variant that still allows for the ecs flag. 
This commit differs from the 6.7 variants in that ecs flag will 
now default to true. 

6.7: `ecs` : default `false`
7.x: `ecs` : default `true`
8.0: no option, but behaves as `true`

* Revert "Ingest node - user agent, move device to an object (#38115)"
This reverts commit 5b008a3.

* Revert "Add ECS schema for user-agent ingest processor (#37727) (#37984)"
This reverts commit cac6b8e.

* cherry-pick 5dfe193 
Add ECS schema for user-agent ingest processor (#37727)

* cherry-pick ec8ddc8 
Ingest node - user agent, move device to an object (#38115) (#38121)
  
* cherry-pick f63cbdb (with manual merge fixes)
Dep. check for ECS changes to User Agent processor (#38362)

* make true the default for the ecs option, and update 7.0 references and tests

Here is an example that adds the user agent details to the `user_agent` field based on the `agent` field:
