Issues with idom.run and SharedClientStateServer

[rmorshea]

@jmtaysom was having some issues with idom.run when using Sanic as well as with Sanic's SharedClientStateServer (previously discussed here).

[rmorshea]

@jmtaysom what version of Sanic are you using?

[jmtaysom]

Sanic 21.12.1

[rmorshea]

IDOM presently requires sanic>19,<19.12 - see here for more info. The other async server implementations should work fine without this limited range of versions.

Again, apologies for all these limitations. I'm presently working on a PR which will address most of the problems we've talked about:

• Rework idom.run
• Remove SharedClientStateServer
• Fix limited support for sanic
• etc.

[rmorshea]

Also, apologies for the sweeping changes here, but SharedClientStateServer is slated for removal since it doesn't work with multi-process web servers. Instead we would need to provide a more robust solution that would work across processes and hosts - probably using something like Redis.

[jmtaysom]

That makes a lot of sense. If it is slated for removal I would remove it from the beginning of the tutorial just to not confuse people.
