When no elements are present in the HNSW tree, we return an error saying so. However, we only need to return nil result.

Currently when we do queries like `func(uid: 0x1) @filter(type)`. We
retrieve the entire type index. Sometimes, when the index is too big,
fetching the index is quite slow. We realised that if we know we only
want to check few `uids` are of the same, then we can just check those
`uids` directly. Right now we are hard coding the number of `uids`
threshold. This could be improved with a more statistical based model,
where we figure out how many items does the type index have, how many we
need to check.

We call txn.Update() once the transaction has finished. This moves all
the uncommited posting lists to a delta map in the txn. This can cause a
deadlock with runMutation. Mostly we have seen it when a transaction has
a timeout. RunMutation keeps on going, while txn.Update() gets
triggered. This PR fixes it by not calling txn.Update() if the
transaction has failed. We would futher look into cancelling runMutation
at that time too.

Add cache to dgraph.type predicate. This would significantly help
improve @filter(type) queries.

When we run CD pipeline, it pushes Docker images to dgraph/dgraph Repo.
There are situations when we want to push images to a different repo
(for example to create a custom build) which we do not plan to make GA.
Now we are exposing a workflow input `custom-build` which is false by
default. When it is checked, then images are pushed to a repo called
`dgraph-custom` instead of our official repo dgraph/dgraph
