Support ingesting SRT streams that don't have stream id

[mekya]

Ant Media Server expects to have streamid in the srt url as follows:
srt://example.antmedia.io:4200?streamid=LiveApp/stream1

Unfortunately, some old SRT encoders or softwares still don't support streamid.

Solution:
Let Ant Media Server have a configuration parameter which is an application name that ingests SRT streams without having streamid. Secondly, streamid can be generated from the peer IP address so that it may be estimated.

Objection: Peer IP address may cause some problems if there are more than one publisher is coming from the same instance. Then there may be index suffix for the streamid.
