Bug 35841: Change wording to indicate request to cancel

1. APPLY PATCH
2. Update circ rules "Default waiting hold cancellation policy" to allow cancellation of holds.
3. Put some holds onto a patron account, Make some waiting holds and have others be any other status besides waiting.
4. Log in to the OPAC as that patron.
5. Go to your account details and look at the Holds tab.
6. You should see a 'Request to cancel' button for all waiting holds.
7. You should see a 'Cancel' button for all non-waiting holds.
