Create threads in the start() method rather than the create()
method, so that if the bootstep is stopped and restarted, a fresh
thread is created.

Fixes #397.

This reverts commit 1ad6900c.

The `master_doc` variable in `doc/conf.py` was accidentally
renamed to `main_doc` in #356. It is a Sphinx configuration
variable and is not related to the name of the main branch.

Instead of reverting it back to `master_doc`, rename it to
`root_doc`, which is the new name of this variable in Sphinx 4.
Consequently, we also now depend on Sphinx >= 4.

The intersphinx URL for the `requests` package was broken by #356.
It was a redirect anyway, so update to using the new target URL.
