Add the ability to replay failed mutations

[gbitaudeau]

Is your feature request related to a problem? Please describe.

As describe on #3259 , mutation errors can happen for various reasons.

Even through the DataStore does its best effort to replay mutations in case of errors, sometimes mutations can't be replayed and in this case the DataStore content is no longer the same as the server content with no way to correct it.

Describe the solution you'd like

A nice feature would be to help developers to replay or correct failed mutations.

Few ideas to do that :

• add a mutationErrorHandler to DataStoreConfiguration which can force a mutation to be kept by datastore giving a retry delay, a retry priority (if other mutations should be sent before this one will be retried) or something like that
• persist a "mutation on error" list which can be consult and easily retried
• ...

Describe alternatives you've considered

Actually, to "replay" mutation we follow this flow :

1. clear the DataStore
2. wait it to be full sync
3. compare it with our local base and replay all missing creates / updates / deletes again (using DataStore.save/delete )
