run-tests: use a small timeout for chg instance There is case where the test runner fails to clean up the temporary files in that case, spawned chg instance can stay around for 1 hours. Getting them to shut down sooner cannot hurt. (We should also use a more robust approach for this cleanup) Differential Revision: https://phab.mercurial-scm.org/D11227

run-tests: do not inherit file descriptor when running a command This is one of the difference between python2 and python3 and could have been a reason why test hang with python2 + chg. This does not seems to help the hanging issue at all… However, now that this is written lets reduce the difference between python2 and python3.

dummyssh: make sure we don't inherit files descriptor to the children This is one of the difference between python2 and python3 and could have been a reason why test hang with python2 + chg. This does not seems to help the hanging issue at all… However, now that this is written lets reduce the difference between python2 and python3.

tests: make test-serve works on system that allow user to bind low port It is possible to encounter linux system configured in a way that allow port < 1024 to be bound by any users. So we update a test to focus more on the actual test: "resolving `daytime` to an actual port number. The new auto-scaling CI runner provided by clever cloud is doing so. This is the initial motivation for this change, but it seems useful anyway. Differential Revision: https://phab.mercurial-scm.org/D11228
