Describe your environment
Mac OS Catalina 10.15.6 (19G73)
Darwin-19.6.0-x86_64-i386-64bit
Python 3.7.7
Installed packages:

opentelemetry-api                      0.12b0    OpenTelemetry Python API
opentelemetry-ext-honeycomb            0.5b0     Honeycomb Exporter for OpenTelemetry
opentelemetry-instrumentation          0.12b0    Instrumentation Tools & Auto Instrumentation for OpenTelemetry Python
opentelemetry-instrumentation-botocore 0.12b0    OpenTelemetry Botocore instrumentation
opentelemetry-instrumentation-pymongo  0.12b0    OpenTelemetry pymongo instrumentation
opentelemetry-instrumentation-requests 0.12b0    OpenTelemetry requests instrumentation
pymongo                                3.11.0    Python driver for MongoDB <http://www.mongodb.org>

Steps to reproduce
any find operation where the number of documents to be returned exceeds the batch size on the cursor:

from pymongo import MongoClient
from opentelemetry import trace
from opentelemetry.trace import TracerProvider
from opentelemetry.instrumentation.pymongo import PymongoInstrumentor

trace.set_tracer_provider(TracerProvider())

PymongoInstrumentor().instrument()
client = MongoClient()
db = client["MongoDB_Database"]
collection = db["MongoDB_Collection"]
collection.find({'batch_size': 1})

What is the expected behavior?
Spans with names like mongodb.getMore.1

What is the actual behavior?
