Remove rate limiting on webapi/ping and webapi/connectionupgrade (#42799

)

The limits on these endpoints can cause issues with legitimate use
cases trying to establish large numbers of connections from a single
host(i.e. Ansible Tower). Extending the limits would likely result
in a bar that constantly needs to be raised as clusters with this
workflow become larger. Instead the limits were removed entirely.
