We're trying to consolidate the field names under checkpoint.* and file_hash is not an existing field. This removes the field and keeps the data in the appropriate ECS field. Also adds support for SHA-256, which the checkpoint supports, but it's not documented in the CEF exporter.
This renames / changes types on some custom fields under checkpoint to align with the names used in Check Point logs (not CEF), so that the documents generated by the CEF module and the upcoming checkpoint module are compatible.
That's the correct name for this field.

Is is this already a number in the event produced by the beat? Looks like it should be since it comes from deviceFlexNumber1 which is a long from the cef processor.

This PR makes some changes to CEF module's custom mappings for Check Point devices to ensure compatibility with the upcoming checkpoint module. Check Point has its custom log format, for which a new module is being prepared. The idea behind this new module as well as CEF custom mappings for Check Point (this PR), is to use ECS whenever possible and map the rest under checkpoint.* using the original field name from Check Point. In the original PR for CEF, a few mistakes had been done in field names and types. Also taking the opportunity to change some ECS mappings. Related elastic#16907 elastic#17682 (cherry picked from commit 4f6da4f)

What does this PR do?
This PR makes some changes to CEF module's custom mappings for Check Point devices, to ensure compatibility with the upcoming checkpoint module.
Check Point has its custom log format, for which a new module is being prepared. The idea behind this new module as well as CEF custom mappings for Check Point (this PR), is to use ECS whenever possible and map the rest under
checkpoint.*using the original field name from Check Point.In the original PR for CEF, a few mistakes had been done in field names and types. Also taking the opportunity to change some ECS mappings.
Why is it important?
We want both CEF an checkpoint modules to define and populate the same fields, ECS and proprietary, and avoid having a breaking change in the future.
