Auto increment id for accesstoken table is not sufficient for large applications

[oreh]

Currently, the PK of accesstoken table is using int type (as default django table id does). But this 32-bit field can only hold around 2 billions records. The keys will be used out in a year if you have 10 millions users who generate new keys on a daily basis.

Can we change the type from int to bigint? Or even better, can we use 'token' as the PK?

We're currently planning to support both django1.7 and south1.0 migrations, so we prefer to postpone the resolution of this issue after that.

I'd like to change all IDs to use BigAutoField but this requires Django 1.10 so we might not be able to do it for a while.
