feat: changed behaviour calculating the time channel will remain in wait state

[gabheadz]

Description

The time the channel will remain in waiting state after socket disconnection is being governed by the parameter max_age, which is used to define token life.

This change proposes to define separate parameters to control how much time (if any) a channel should remain in waiting state depending on how the connection between client and server terminated.
