Make host and port configurable

reporter = Reporter(config={"agent_host_name": "some-host", "agent_port": 9999})

Fixes matrix-org/synapse#13399 (comment)

Dev notes

$ source /Users/eric/Documents/github/element/synapse/.venv/bin/activate
$ pip install maturin
# builds the crate and installs it as a python module directly in the current virtualenv. Note that while maturin develop is faster, it doesn't support all the feature that running pip install after maturin build supports.
$ maturin develop

# Sends spans over to your local Jaeger instance
$ python test.py

This is part of test.py 🤷

deref on an immutable reference

The check looks to be spurious, and caused by rust-lang/rust-clippy#8971
