tests: use pytest-rerunfailures (#253)

mgorny · web-flow · commit 05c749666f0f · 2023-04-16T08:49:27.000+02:00
Use pytest-rerunfailures plugin to attempt to rerun failing tests
up to 5 times.  While this doesn't solve the underlying issue, it should
keep the CI green and detecting real issues until we figure out how
to solve it properly.
