Add custom collection names

[totemcaf]

Description

Let use a custom name for Outbox and Snapshots collections.

Affected Components

• mongodb.Outbox
• mongodb_v2.EventStore

Related Issues

None

Solution and Design

This is a replication of the available functionality to set event and streams collection names.

Added an Option to set the custom name:

• outbox.WithCollectionNames
• mongodb_v2.WithSnapshotCollectionName

The WithSnapshotCollectionName is added to kepp compatibility with exitent WithtCollectionName (and because I want to review if Snapshot should be part of this EventStore or should be another store).

Steps to test and verify

1. Create an event store with custom name: NewEventStore(url, db, WithSnapshotCollectionName("foo"))

2. Check in database the collection created is foo

3. Create an outbox with custom name: NewOutbox(url, db, WithCollectionName("foo-outbox"))

4. Check in database the collection created is foo-outbox
