Add transactional adapter support for mongoose

[GO-DIE]

mongoose is a popular mongodb client package that is used by many people including myself, and I am eager to add an official transactional adapter to mongoose.

Hi, I was planning to add support for plain mongodb at some point (or welcome a contribution).

In terms of mongoose - I don't know if you're aware, but they offer a built-in transaction propagation with AsyncLocalStorage (i.e. the very same thing that a @nestjs-cls/transactional plugin would offer, so the only benefit would be the option to use the @Transactional decorator)

Yes, I understand, but I don't think there is a conflict because mongoose's support for AsyncLocalStorage makes us easier to provide a transaction adapter for us to use the @transactional decorator feature.

@GO-DIE Would you like to have a go at implementing it? I am definitely open to contributions.

I found some free time and put together a mongoose adapter. Feel free to test it for your use-case.

@nestjs-cls/transactional >= 2.4.0 is required.
