Race Condition Using KV Tests Against Performance Replica

Hello,

I am working on an engagement where the tests are targeting a performance replica.

The secret engine is created successfully but when there is load against the cluster replication in not fast enough to get the newly created mount out to the performance secondary before the load test moves on.

I would like to have a `setup_delay` that can be configured for KV and KV V2 secret engine tests, similar to what is already available in the PKI secret engine tests.

Thank you.

Start by locating the PKI secret engine tests and their existing setup_delay configuration, then find the corresponding KV and KV V2 test setup. Add equivalent configurable delay support for those tests and verify that the delay occurs after mount creation so performance replicas can receive it before load begins.
