MIN_TOKEN_LIFE_SECONDS is the number of seconds that the token provided
must be valid for to be used when making authentication requests. 1
second has always been a dumb number and was not based on any existing
value.
Because a user token may be reused by a service to make requests on
behalf of a user if the token is valid when sent it may not be valid for
the life of the request.
2 minutes is also an arbitrary value, but it should allow plenty of time
for service requests to complete before being rejected.
