This PR adds a stream processor modify method. It can be used to modify the definition of a stream processor.

I also manually tested this change against the ASP service with the below:

AtlasStreamProcessing> sp.createStreamProcessor("testedit2", [{$source: {connectionName: "DemoKafka", topic: "t1"}}, {$project: {device_id: 1, foo: "bar"}}, {$project: {_stream_meta: 0}}, {$emit: {connectionName: "DemoKafka", topic: "testedit2"}}])
Atlas Stream Processor: testedit2
AtlasStreamProcessing> sp.testedit2.start()
{ ok: 1 }
AtlasStreamProcessing> sp.testedit2.stop()
{ ok: 1 }
AtlasStreamProcessing> sp.testedit2.modify([{$source: {connectionName: "DemoKafka", topic: "t1"}}, {$project: {device_id: 1, foo: "BAZ"}}, {$project: {_stream_meta: 0}}, {$emit: {connectionName: "DemoKafka", topic: "testedit2"}}])
{ ok: 1 }
AtlasStreamProcessing> sp.testedit2.start()
{ ok: 1 }

AtlasStreamProcessing> sp.testedit2.stop()
{ ok: 1 }
AtlasStreamProcessing> sp.testedit2.modify([{$source: {connectionName: "DemoKafka", topic: "t2"}}, {$project: {device_id: 1, foo: "BAZ"}}, {$project: {_stream_meta: 0}}, {$emit: {connectionName: "DemoKafka", topic: "testedit2"}}])

Hi @addaleax, I'm ready to merge :) It appears I don't have write access to merge my PR. Are you able to hit merge for me? Thanks in advance.
