`airflow pools set` fails with argparse error

Apache Airflow version: 1.10.14 and 1.10.15

Environment:

• Cloud provider or hardware configuration: Docker
• OS (e.g. from /etc/os-release): apache/airflow:1.10.15-python3.8
• Install tools: poetry

What happened:

Based on a warning from Airflow, I decided to change from

airflow pool -s mypoolname 2 mypooldesc

to

airflow pools set mypoolname 2 mypooldesc

The first command was successful while the second resulted in the following error:

airflow_1   | Traceback (most recent call last):
airflow_1   |   File "/home/airflow/.local/bin/airflow", line 37, in <module>
airflow_1   |     args.func(args)
airflow_1   |   File "/home/airflow/.local/lib/python3.8/site-packages/airflow/bin/cli.py", line 302, in pool_set
airflow_1   |     _pool_wrapper(args, set=(args.name, args.slots, args.description))
airflow_1   | AttributeError: 'Namespace' object has no attribute 'name'

What you expected to happen:

I expected it to have the same effect as running the to-be-deprecated version.

How to reproduce it:

1. Start up Airflow
2. Attempt to create a pool using airflow pools set <name> <number of slots> <description>

Anything else we need to know:

The error occurs consistently. Switching back to the to-be-deprecated version works every time.
