[Fleet] Make Agent Policy inputs ids unique

[nchaulet]

Description

During the effort of reporting agent status, we found that input ids are not unique, we plan to use input id to report policy status, so we should probably fix this.

Current Policy

Possible solution

We could prefix the input id by the input type
@kevinlog Does this will impact endpoint as the input id will not match the package policy id anymore?

We'll need to access the package policy ID in some predictable way, so if they're prefixed, we could strip that and use it to make changes to the policy. Will this change the policy APIs in Ingest? Will we now make updates using the new input ID with the prefix?

@paul-tavares @parkiino can you also comment on the above? Any other ways you'll see it impact our UI?

Yes the package policy API be impacted and only accept the package policy Id as identifier /package-policies/{packagePolicyId}
I guess we can have some "magic" on our side to support both package policy id and input id but if we can avoid that.
