Adding message to run/rerun, other interface tweaks

[vsoch]

This pull request will address the following issues:

• Allow for "leading" part specification of task id #28 that will match a partial task id
• run: add -m|--message (or -d|--description) #27 to add the ability to specify a message to run or rerun
• start: Please at least report the address to visit #26 adding the address / port to the qme start (note this is normally there when debug is on)

@yarikoptic please review! I tried to just add you as a reviewer to the repo but it didn't give me the option, I suppose I forgot how to do that :P

Just added QME_MESSAGELEVEL to control the logging level.

Invite me as a collaborator

Consider using common prefix for all env var related to logging, eg shorter QME_LOG_. Then you could uniformly add more settings as needed. I will also appreciate it personally since that is the convention I used in a good number of projects

Good idea @yarikoptic, but we can add that in a separate PR when there is some refactor of the logger (out of scope here).

Left some comments, which might be irrelevant but might be addressed for perfection ;-)

[vsoch]

@yarikoptic ready again for review! For the logging I can do that in another PR.

[yarikoptic]

Left a follow up question to one comment which you marked resolved

[vsoch]

Sorry that I missed the bit about the host - it's added now! :)

[yarikoptic]

Sorry to be the pain and not properly describing my intentions, I should have had add a suggestion but ATM hard on the phone.

Before using host variable, don't you need to move it's final definition there? (And use also below), ie

host=host or QME_HOSTNAME

[vsoch]

Oversight on my part - fixed now!

[yarikoptic]

Thank you! Cheers
