Adding bucket notifications feature

[RodrigoFerretti]

Description

Notifications can be used to send information about changes to objects in your buckets to Pub/Sub.

Proposal

Integration with Pub/Sub will happen either with emulator APIs or GCP. Information about Pub/Sub emulator can be found here.

To emulate the official Google Cloud bucket notification, the new routes will:

• insert new bucket notification
• delete bucket notification
• get bucket notification
• getbyid bucket notification

Existing route of upload will:

• send notification to Pub/Sub topic whenever a object is inserted into a bucket

This is still a draft and there is a lot of study to do!

Official information about Pub/Sub notification for Cloud Storage can be found here.

Any chance this is happening? It would be a very useful addition.

Hi! Got busy at work and forgot about this, my bad. I will take a look to see what it needs for this pull request to be ready for review. If I am not mistaken, there are only some test methods to be done. It also needs documentation about the process of using it with the emulator. Hopefully is done by next week. :)
