Added initial checkpoint to graphql replication

[lavaxun]

This PR contains:

1. Initial checkpoint for GraphQL Replication: pull & push.
2. This PR is inspired by couchdb initial replication from another PR: Feature: initialCheckpoint for Couchdb #5461

Describe the problem you have without this PR

1. Currently only the couchdb supported initial replication. However GraphQL replication does not support this.

Thank you for the PR. Can we add a test to that? Also docs must be updated.

ya sure. I'll try to add the test cases around the initialcheckpoint next week or so.

I'm currently using Github codespace for this, however it hits a roadblock when doing npm install .
Seems like there is something to do with the premium plugin.
any idea to solve this?

Do you install premium for this PR? Because the changes are only for the core stuff and therefore you should not need premium.

Do you install premium for this PR? Because the changes are only for the core stuff and therefore you should not need premium.

The PR was based on the main branch and was created using the GitHub built-in codespace. Shouldn’t have the premium plugin installed I guess?

Will have to look further into the npm install issue again in future.
but will close this PR for now due to busy schedule recently. Sorry about that.
