Migration Guide from rsync to unison as default

[EugenMayer]

What steps need to be done when we change the default of docker-sync to unison?

• excludes need a different syntax or the usage of sync_excludes_type: 'Name'
• group-id mapping needs to be removed from the docker-sync.yml
• notify_terminal does only notify once on the initial not the subsequent syncs

• remove fswatch_strategy option to prevent issues like Setup a fs monitor inside the container #209
• remove other specific options of rsync
• use sync_strategy: 'unison'

BTW, while working daily with unison and really happy with it, unison has still some instabilities. I always have a log window with debug mode activated displayed on my screen to ensure files are correctly synced. Most of the time, a simple (or multiple) restart fix the issue, but unison + daemon will hide any information to the end user of eventual problems.

well we will provide logs here #65 (comment) so you can still tail -f and have the same thing. I also use unison only these days and i have very little to none glitches at all. And we are talking about 5-7 different guys using it on different pretty large projects with different stack types ( huge web stacks, java stacks, ruby stacks ). So i would really call this one "stable enough"
