Bug: flaky plugin - unexpected keyword argument 'reruns'

What happened:

• Building dask from source using conda on arm64 machine
• Command used- conda env create -n dask-dev -f continuous_integration/environment-latest.yaml (error)

Error

Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound: 
  - bcolz
  - crick

What you expected to happen: Able to create the environment without any missing packages

Anything else we need to know?: I commented the bcolz, crick in the environment-lates.yaml file, and the environment was created successfully, though few tests failed.

Updated tests failures

• conda create -n dask python dask` - successful env creation

Thanks, @jrbourbeau all the test cases passed. It would be great I think to document this.

[jsignell]

pytest-rerunfailures is already included in when you do python -m pip install -e ".[complete,test]" as recommended in the Development Guideline. I am going to close this, but if you think there is somewhere where we can be more explicit please open a pull request!
