Module timeout 

Timeout constants and hierarchies. Timeout constants, organized into nested modules named after the API trait, service, or struct whose timeouts it holds.

const_assert!s are used to enforce our timeout hierarchies; e.g. each timeout along a request chain must be shorter than the one enclosing it.

Principles for tuning:

• When a timeout increase is needed: prefer to raise the timeout for a specific server or client method that needs it, rather than the global default.
• Be careful when decreasing timeouts baked into enclave programs - if it cannot be overridden via CLI, there is no way to backtrack if the decrease was too aggressive. Wire through a CLI arg before decreasing the timeout.
