200ebbd47e proposed schemas for events 
This is a proposal to add schema, timestamps and unique ids to
events.  For now just JS ones but I propose to do these for all
events the server sends that might be end user consumed.

These exist to help the user identify a message even if it was
sent to a 3rd party system, the schema will be translatable to
a well known url like https://nats.io/schames/jetstream/event/v1/obs_ack.json
or to another wll known identifier like a NATS subject name

We'd publish JSON schema documents at these well known locations
describing each key and so forth

dd116fcfd4 JetStream first pass basics. 
This is the first checkin for JetStream. Has some rudimentary basics working.

TODO
1. Push vs pull mode for observables. (work queues)
2. Disk/File store, memory only for now.
3. clustering code - design shaping up well.
4. Finalize account import semantics.
5. Lots of other little things.
