Fix bug: sshMaxArg main function was using only the first profile

[aryoda]

• Now all profiles with ssh mode are probed for the max ssh cmd length
• Code doc for config property "sshMaxArgLength" updated (used to generate man pages)
• Fix some minor documentation issues

• Unit tests did work

Output is now:

> python3 sshMaxArg.py
Profile 1 - Main profile: Mode = local
Profile 2 - profile 2: Mode = local
Profile 3 - test2config: Mode = local
Profile 4 - ext dev test: Mode = local
Profile 5 - ssh-hello-world: Mode = ssh

Very fine. It's a pleasure to work with you together. I learn a lot. (And hopefully improve my English.) ;)
