add support for upsert (findOneAndUpdate)

[bwgjoseph]

Provide a way to take in options (e.g params.ottoman) where it allows user to specify upsert option for patch method

See findOneAndUpdate and FindOneAndUpdateOption

service.patch(null, data, { query: { name: 'hello' }, ottoman: { upsert: true, new: true } });

[bwgjoseph]

updateMany API supports passing in UpdateManyOptions option where we can pass in through params.ottoman and process it in

feathers-ottoman/src/index.ts

Line 257 in 3e961a1

_getOptions(filters: Filters, method: Methods = 'default'): Query {

Unfortunately, that would means that if params.ottoman is present, we would have to call non KV operation to update the document by using either findOneAndUpdate or updateMany
