Short OAuth token lifespan (~ 5 mins) leads to unnecessary fetch of a new token #309

- I agree to the terms within the OpenFGA Code of Conduct.
Describe the problem you'd like to have solved
The current implementation of the token validity validation treats tokens that expire in the next 5 minutes as not valid anymore.
Our token lifespan is 5 mins, so with every request to OpenFGA, the client requests a new token.
In my opinion, the 5-minute threshold that the client uses is a very long time. In our microservices environment, we use a 30-second threshold and have never had a problem with it.
Describe the ideal solution
Would it be possible to reduce this threshold or make it configurable? This would allow to continue using very short-lived tokens, which would improve security.
Alternatives and current workarounds
Increase the token lifespan.

Additional context
Just as a side note, the default value for token lifespan in Keycloak is 5 minutes.
