Provide More Specific Amount of Time When Introducing a Change

[danielhelfand]

It takes an appreciable amount of time for changes to be introduced that may cause a user to question whether what he or she has done is working. It would be helpful to estimate how long changes take when it is mentioned that changes will take a while. An example from the Mutual TLS section is below:

Note: It may take some time before the mesh begins to enforce the policy. If *you do not see the expected behaviors, wait a few more moments and then try *again. Patience is a virtue.

There are also sections like Routing that don't warn the user of that changes will take appreciable time to take affect. The workshop should always warn the user in this case.
