bug: http input keepaliveTimeout in CRD transforms to keepLive_timeout, should be keepalive_timeout

[applike-ss]

Describe the issue

The http input in the CRD has a keepaliveTimeout property which the operator makes keepLive_timeout in the fluent config secret.
However it should be keepalive_timeout as per the docs here: https://docs.fluentd.org/input/http

To Reproduce

Create a fluentd.fluent.io/v1alpha1 Fluentd with one http globalInputs and specify the keepaliveTimeout property.

Expected behavior

Should translate to keepalive_timeout in the compiled fluentd config

Your Environment

- Fluent Operator version: v2.4.0
- Container Runtime: doesn't matter in this case
- Operating system: doesn't matter in this case
- Kernel version: doesn't matter in this case

How did you install fluent operator?

helm chart from https://fluent.github.io/helm-charts - shouldn't matter though
