Is it possible to turn the token field names configurable by settings?

[feslima]

Hi, thank you for the project and work!

I mean, for example, when obtaining the token pairs, we perform the mutation like this:

mutation TokenAuth($username: String!, $password: String!) {
  tokenAuth(username: $username, password: $password) {
    token
    refreshToken
    payload
    refreshExpiresIn
  }
}

Suppose I want to rename the field token to access and refreshToken to refresh and perform the mutation like this:

mutation TokenAuth($username: String!, $password: String!) {
  tokenAuth(username: $username, password: $password) {
    access
    refresh
    payload
    refreshExpiresIn
  }
}

I saw that the name definitions are done here:

django-graphql-jwt/graphql_jwt/mixins.py

Line 21 in 704f24e

cls._meta.fields["token"] = graphene.Field(graphene.String, required=True)

and here:

django-graphql-jwt/graphql_jwt/mixins.py

Line 24 in 704f24e

cls._meta.fields["refresh_token"] = graphene.Field(

Is it possible to make these fields configurable via settings definition or is it a breaking change?
