feat(DASH): Remove MIN_UPDATE_PERIOD_ to achieve better latency in Live

[avelad]

Many LL streams use 2 seconds segments, so we have to ensure that these streams work correctly.

I really don't know if it makes sense to have MIN UPDATE PERIOD because it prevents it from updating when appropriate, I've tried to see the history and I can't find why it was added...

In HLS, with LL we can update with the size of the last segment, and this is sometimes as little as 250ms.

The history of this goes all the way to the beginning. We were concerned that poorly-formatted DASH content could have an unreasonably-short update period, leading the client to misbehave. We wanted to avoid updating too frequently.

If you would rather have the new feature be the removal of this internal restriction, that's fine with me. The DASH ecosystem has grown up quite a bit since 2014.

So, I'll delete it! thank you!

Looks like some tests are failing and need to be updated.
