Redundant "Requirement already satisfied" output in 20.3b1 #9117
Description
Environment
- pip version: 20.3b1
- Python version: Python 3.7.9
- OS: Ubuntu 16.04
Description
Starting with version 20.3b1, pip spams many Requirement already satisfied messages.
Expected behavior
In earlier versions the messages was just printed once per package, which was much nicer behavior.
How to Reproduce
A simple example pip install kubernetes plotly protobuf six (on second execution):

For instance the message that six is already satisfied is shown 8 times.

In one of our large projects for instance, the number of output lines has increased from 226 messages to 535 messages. Also, the new behavior has an actually observable performance impact:
- 2.3 seconds in 20.2.4
- 3.8 seconds in 20.3b1
