Implement populating schemas for a post, fact check etc during creation or updation

[deshetti]

Currently, we are populating all the schemas for a Post, Fact Check, etc during retrieval on dega-api. This is an expensive query and is more performant to populate it as a new field during creation/updation of a post.

PRO:

• Performance of the read queries in dega-api improves significantly, especially the ones which are more involved like the fact-checks

CONS:

• Increased complexity when creating/updating a post. This should still be manageable as long as the read queries which are more frequent are performant.
• When updates are made to fields like organization, user, etc, we have to repopulate all the related schemas for posts. A workaround for this would be to provide the ability to manually retrigger generation of all the schemas for posts in a particular space. This way, administrators for a particular space could trigger updating the schemas manually whenever there is a change that automatically doesn't generate the schemas.
