Addresses the LRO_RESPONSE_HEADER guideline.

This commit ensures the following invariant in managedHsm.json:
```
If an operation can return a 202 Accepted response, then we insert
'"x-ms-long-running-operation": true,' directly below the operationId,
and we insert a Location header in the operation as well as the
corresponding example.
```
