Support 'parent link' field in Integrations for other issue types.

Aha recently added support for the Jira 'Parent Link' field in Integrations, and this was delivered via this ticket. https://big.ideas.aha.io/ideas/APP-I-7115

Turns out that this integration will only support the Parent Link field for the Initiative issue type in Jira.

In my use case, I have multi level initiatives, and because I'm using Jira Plan, I have to have a different issue type to represent each level in this Initiative hierarchy. So at the lowest level, I have a custom issue type that I link the Epic to using the Parent Link field.

Aha does not support this use case when using the Parent Link field, and I'm requesting that the integration is extended to support Parent Link field for other issue types.
