Auto set contenty-type in PANG

[patuwwy]

What?
When Instance has overwritten output to topic, ie with command

si seq start --output-topic test-topic

but content-type is unknown, will set content-type to match topic content-type (if exists) or set to default content-type (application/x-ndjson)

So, to set prefered content-type one should create topic first

si topic create test-topic -t text/plain

and then

si seq start <SEQ> --output-topic test-topic

otherwise topic will be created with default content-type

Why?
If Sequence's output Content-Type is not defined there is no possibility to redirect output to topic
