[BUG] TV sample app does not receive DNSSD updates

[cliffamzn]

Reproduction steps

When a device is advertising over dns-sd and the TX bits change (device name) a message is sent out to indicate that the old advertisement should be expired and the new one should be used.

In the current implementation of the casting app, we stop listening to updates after the discoveryDurationSeconds timeout. This causes us to miss messages and Android seems to fall back to the cached value of the DNS advertisement.

We need to change the usage pattern here so that clients stop the discovery manually after it is started and keep it active for the lifetime they need it for.
