Define input variable types

[mtojek]

This issue defines all input variable types and is a meta ticket for potential adjustments.

Right now we have:

• text
• password
• bool
• integer
• yaml

New type: duration

Based on discussion here: elastic/integrations#266 (comment)

[ruflin]

It will be great to have it defined in the package spec for validation but also for documentation purpose (single source of truth)

[mtojek]

They are already defined. I linked it above: https://github.com/elastic/package-spec/blob/master/versions/1/data_stream/manifest.spec.yml#L24

+1 for adding duration to the accepted types, as suggested in #44 (comment).
APM is using the custom policy editor, but the type and default values are defined in the package. Given the type restrictions, the package can only define a text input where duration is expected. Without duplicating the knowledge that a specific field should be a duration, it is currently not possible to add UI validations for durations in the way needed. This is currently causing problems related to fixing elastic/kibana#121640.

A proper duration type would also help address elastic/integrations#6684.

[andrewkroh]

For the duration data type, the ability to specify a minimum value for validation purposes (in both the UI and API) would be beneficial. We have Agentless integrations that require a floor on their interval to prevent API abuse, so I'd like to reject values less than 1m, for example.

[StacieClark-Elastic]

For some integrations, we should consider maximums as well for both interval and initial interval. These affect the amount of memory required.

I have opened a spec change PR to begin the process of adding duration. #948
