Add openlineage adapter

[skrawcz]

Note: I updated the materializer docs because we missed adding @dataloader() and @datasaver() to them
under the materialization concepts page.

This adapter emits OpenLineage events.

# create the openlineage client
from openlineage.client import OpenLineageClient

# write to file
from openlineage.client.transport.file import FileConfig, FileTransport
file_config = FileConfig(
    log_file_path="/path/to/your/file",
    append=False,
)
client = OpenLineageClient(transport=FileTransport(file_config))

# write to HTTP, e.g. marquez
client = OpenLineageClient(url="http://localhost:5000")

# create the adapter
adapter = OpenLineageAdapter(client, "my_namespace", "my_job_name")

# add to Hamilton
# import your pipeline code
dr = driver.Builder().with_modules(YOUR_MODULES).with_adapters(adapter).build()
# execute as normal -- and openlineage events will be emitted
dr.execute(...)

Note for data lineage to be emitted, you must use the "materializer" abstraction to provide
metadata. See https://hamilton.dagworks.io/en/latest/concepts/materialization/.
This can be done via the `@datasaver()` and `@dataloader()` decorators, or
using the `@load_from` or `@save_to` decorators, as well as passing in data savers
and data loaders via `.with_materializers()` on the Driver Builder, or via `.materialize()`
on the driver object.

TODOs:

• move adapter to h_openlineage.py
• write example
• write docs for adapter
• write some tests

Changes

• adds h_openlineage
• adds example
• updates docs

How I tested this

• runs locally
• shows up in marquez

Notes

Checklist

Looks good! Downloaded, played around with it, and fixed a small bug.

I think we want to veresionthe Hamilton Facets/think about more nuanced facet stuff, but for now this is a good bridge.
