v8

Description of the Change

This PR adds a 'TIP' to restart the app when enabling ssh:

➜  out git:(v8) ✗ ./cf-cli_macosarm disable-ssh my-app
Disabling ssh support for app my-app as my-user...
OK

➜  out git:(v8) ✗ ./cf-cli_macosarm enable-ssh my-app 
Enabling ssh support for app my-app as my-user...
OK

TIP: An app restart is required for the change to take effect.
➜  out git:(v8) ✗ ./cf-cli_macosarm enable-ssh my-app
Enabling ssh support for app my-app as my-user...
ssh support for app 'my-app' is already enabled.
OK

TIP: An app restart may be required for the change to take effect.

Complies with style guide

Why Is This PR Valuable?

As a cloud foundry operator I often get questions from customers about cf ssh "not working", because it is not obvious that a restart is necessary.
