Schema Deprecation
Use the deprecate option when defining any field or enum value.
- Provide a binary value to give a deprecation reason
 - Provide 
trueto just mark it as deprecated 
An example:
query do
  field :old_item, :item, deprecate: true
  field :another_old_item, :item, deprecate: "still too old"
end
You can also use the deprecate as a macro inside a block, for instance:
field :age, :integer do
  deprecate
  arg :user_id, non_null(:id)
end
With a reason:
field :ssn, :string do
  deprecate "Privacy concerns"
end
Warning: Deprecated fields and enum values are not reported by default during introspection.
