Google-cloud-python: Firestore: FieldValue.increment() feature

[A-Iskakov]

Hello,
I have noticed new feature FieldValue.increment() in the latest Firestore SDK for JavaScript
is it possible to add this feature in google-cloud-firestore?
Many thanks!

Seems like this is addressed with google-cloud-firestore 1.2.0

@GuanacoDevs Yes, the feature was added in #7989.

@tseaver - Could you explain how you use this?

u'test_col': firestore.FieldValue.increment(1)

AttributeError: module 'google.cloud.firestore' has no attribute 'FieldValue'

[tseaver]

@binojohnthomas It looks like the google.cloud.firestore shim module needs updating (I would recommend not using it myself). Instead, use the firestore_v1 package:

```python
from google.cloud import firestore_v1 as firestore
````

I have opened #8173 to track updating the shim module.

@binojohnthomas as a temp solution you can use this way:
from google.cloud.firestore_v1 import Increment
db = firestore.Client()
doc_ref = db.collection(u'collection_name').document(u'document_name')
doc_ref.set({u'test_col': Increment(1)}, merge=True)

@A-Iskakov Thanks - It worked!
