Fix flake8 violations for all files in the asv/plugins/ directory

[dorothykiz1]

We are trying to clean out all the files to follow Flake8 standards

Use this guide below to install flake8 and how to use it.
Flake8 guide

Here are a few steps to follow:

• You will be required to remove the files you would like to work on from the setup. cfg file under the extend attribute .
• Create a virtual environment virtualenv venv venv will be the name for the environment and activate it by running source venv/bin/activate these commands are dependent on the operating system. (These are Linux commands, you can find for windows and macOS online)
• Run pip install flake8 to install flake8
• Run flake8 --exclude="" asv/plugins/ .
• Work on all the highlighted errors

@dorothykiz1, maybe here what you can do is:

• Fix the first few errors in the list (the ones before asv/plugins)
• Split this issue in 3, one for plugins, one for commands and one for extern

What do you think?

[dorothykiz1]

@datapythonista makes total sense,let me do this

[LucyJimenez]

@datapythonista, @dorothykiz1 I'm going to work on this one.
