update to chefspec 4.1.1

[bkw]

syntax updated to use the new chefspec-4.1.0 way of doing things, no functional changes.

• update chefspec and chef dependencies (chefspec-4.1.0 needs at least chef 11.14)
• remove deprecated explicit require of chefspec/server
• change ChefSpec::Runner into ChefSpec::ServerRunner
• construct data bags inside of chef_run block

For details, see https://github.com/sethvargo/chefspec/blob/master/CHANGELOG.md

seems coveralls and chefspec-4.1.0 don't play nicely together just yet. Bummer.

[bkw]

I created chefspec/chefspec#504 for this, in case it really is a chefspec issue.

Coverage remained the same when pulling 3922d31 on bkw:chefspec-4.1.0 into 7ab4273 on TelekomLabs:master.
