FR: firebase.firestore.FieldValue.increment(value)

[REQUIRED] Describe your environment

• Operating System version: all
• Browser version: _____
• Firebase SDK version: 5.7.1
• Firebase Product: firestore

[REQUIRED] Describe the problem

Similar to
firebase.firestore.FieldValue.arrayUnion(value)
firebase.firestore.FieldValue.arrayRemove(value)

would be great if we have option appendValue(n)
where use it only for numbers fields and (n) should be number even positive or negative value.
this will enable us to minimize the number of transactions for counters problem. and even help us to do counter operations on offline mode..

Code Example

  var doc = { a:5, b:10};

 var n = -1; //any number 

 var changeCounter = {a : firebase.firestore.FieldValue.appendValue(n)};

 firestore.collection('col').document('doc').update(changeCounter);

 newDocResult = {a:4, b:10};

Thanks for amazing firestore

As always, I can't promise timelines but this is coming soon. See #1368.

It will be firebase.firestore.FieldValue.increment.
