Feat: jinad integration

[imsergiy]

This is the big one, lot's of changes in this PR related to the connection stream. Would love feedback on my usage of redux and any other suggestions. Planning to polish this just a bit more as well but this is a good place to start.

What's new

• jinad client for latest version of daemon
• testServer to mock jina client
• redux implementation of jinad connection flow
• modified some types to be more clear and hold additional information
• updated tests to work with changes

usage I highly recommend actually running jinad as well for this to get to know the real thing. Test server also works to mock the jinad API.

• navigate to flow view
• Pick a flow
• Press play
• Flow should start
• Within 5-10 seconds, logs should start coming into the dashboard. For now, there is a hardcoded delay and usually a timeout because of https://github.com/jina-ai/jina/issues/1811 and https://github.com/jina-ai/jina/issues/1812
• You should be able to see logs in the stream
• Press stop (square) in flow view to terminate a flow. First request will timeout (again, https://github.com/jina-ai/jina/issues/1811) next request should terminate flow.
