switch to use tiled server

[prjemian]

As noted in an hklpy issue, we need to switch our catalog reference to use tiled server:

from tiled.client import from_uri

# For security, set the API key by setting env var
# TILED_API_KEY rather than putting it in code.

URI = "http://localhost:8020"
client = from_uri(URI)
cat = client["training"]
RE = RunEngine()
# RE.subscribe(cat.v1.insert)  # the old way
RE.subscribe(cat.post_document)

Tiled docs have advice about creating/storing the API key.

We'll need instructions for routine installation of a tiled server for each instrument, and reconfiguration of the instrument package for this change.

Tasks for unit testing

• [ ] start MongoDB server
• [ ] install database with bluesky catalogs for testing
• [ ] Establish API key
• [ ] start tiled server
• [ ] reconfigure RE.subscribe()

Example python code to start a local (no network) tiled server with config for MongoDB server (which is network based):

from tiled.client import Context, from_context
from tiled.server.app import build_app_from_config

config = {
    "trees": [
        {
            "path": "bluesky_runs",
            "tree": "databroker.mongo_normalized:MongoAdapter.from_uri",
            "args": {"uri": "mongodb://localhost:27017/bluesky_runs"},
        }
    ]
}

app = build_app_from_config(config)
context = Context.from_app(app)
client = from_context(context)
