[Security Solution] [Detections] Remove file validation on import rou…
Browse files Browse the repository at this point in the history
…te (#77770)

* utlize schema.any() for validation on file in body of import rules request, adds new functional tests and unit tests to make sure we can reach and don't go past bounds. These tests would have helped uncover performance issues io-ts gave us with validating the import rules file object

* fix type check failure

* updates getSimpleRule and getSimpleRuleAsNdjson to accept an enabled param defaulted to false

* updates comments in e2e tests for import rules route

* fix tests after adding enabled boolean in test utils
