[rfprod]

Describe the bug
Currently functions are not deployed to firebase both from local setup and from CI.

To Reproduce

1. Execute command

firebase deploy --only functions:graphql,functions:login,functions:logout,functions:signup

Expected behavior
Functions are deployed to firebase.

Additional context
Terminal log

i  functions: updating Node.js 10 (Beta) function logout(us-central1)...
i  functions: updating Node.js 10 (Beta) function signup(us-central1)...
i  functions: updating Node.js 10 (Beta) function graphql(us-central1)...

Functions deploy had errors with the following functions:
	graphql
	login
	logout
	signup


To try redeploying those functions, run:
    firebase deploy --only functions:graphql,functions:login,functions:logout,functions:signup

Check this files which have commented code regarding firebase environment and grpc:

• apps/api/src/main.ts
• apps/api/src/app/modules/grpc/grpc-api-client.options.ts

Install required dependencies for grpc support in /functions directory.

Revise .devops directory contents.
