What's needed?

We need to be able to get sensors and sensor data.

Proposed solution

Add a new client methods based as much as possible on the API v0.17, so it is easier to migrate:

• list_sensors()
• receive_sensor_data_samples_stream()

Additional context

• v0.17 sensors metadata and data samples: https://github.com/frequenz-floss/frequenz-api-common/blob/v0.x.x/proto/frequenz/api/common/v1/microgrid/sensors/sensors.proto
• v0.17 sensors RPC calls: ListSensors, ReceiveSensorDataStream
• v0.15 sensors component type: https://github.com/frequenz-floss/frequenz-api-common/blob/59dcdc0146de9b64a5f25f55165617237098a343/proto/frequenz/api/common/components.proto#L37-L38
• v0.15 sensors types: https://github.com/frequenz-floss/frequenz-api-common/blob/59dcdc0146de9b64a5f25f55165617237098a343/proto/frequenz/api/common/components.proto#L107-L132
