Ubuntu 20.04 fixes:
- fixes sshd test
- speeds up examples/{treeping64,tree1024}.py
- debugging hacks/output for testLinkChange
- removes cfs from examples/popen.py
- improves nat in nodelib (netplan fixes?)
- makes some tests executable
- waits for switches to connect in tests to
avoid race conditions
-- adds mn -w option and wait CLI command
Changes:
- REMOVES default "-v" argument for Controller()
and adds verbose(=False) option; avoiding logging
makes it faster
- CHANGES waitConnected to wait for 5 seconds
as documented; we may wish to implement an argument
to -w to set this timeout
Issues?
- There may still be an issue with the ovs-netplan-clean
service causing the boot to hang ;-(
