Allow to delete an object from index only having an identifier

[norkunas]

Description
Currently MeiliSearch\Bundle\SearchService exports method for deleting an entity, but there is no way to delete it having an identifier only. The basic use case - delete hundreds of entities in batch, then dispatch a messenger message to remove them from index, but providing only integers, as you cannot load anymore entities that do not exist.

Basic example

public function removeById(ObjectManager $objectManager, $identifier); // not sure about typehint of $identifier

Other

nothing more.

Hello @norkunas, feel free to implement your need in this package :)

We should have test for this function of course

Looking at how the final ID is generated to be stored to meilisearch, I'm not sure how this could work with composite identifiers..

For a basic use case when no composite is used, we could allow to just pass int/string ID and then in the method retrieve the identifier field of the doctrine entity and convert to the meilisearch format and that would work.

But if composite would be used than we'd need to manually provide the values mapping to which fields they belong and also in the same order that is retrieved to convert the composite..

Maybe a basic use case would be enough for now until someone would show an interest?

Yes, let's keep basic for a first implementation.
