Feature: Feature flags on account (#814) (#815)

* Feature: Feature flags on account (#814)
* Added the new column on account model for managing feature flags
* Added the inbound email flag
* Locked the settings of this eature in account settings based on this
* Encapsulated the feature flaging as a concern. With this, we can re-use the same concern if we introduce this in other models like user or inbox or so.
* Added the features in the account api

* Changed Rails/FilePath style - rubocop issue

* Revert "Changed Rails/FilePath style - rubocop issue"

This reverts commit 3a42d3b9c9b3a2fde8bc7256fd704b6fcaf54040.

* Disabling rubocop on codeclimate as we already have this in CICD
