Can't execute: Malformed tests.yml when environment is present

[lukaszachy]

I am not able to execute test if it sets the environment.

Steps to reproduce:
Plan in file repro.fmf with content

summary:
    Basic smoke test
discover:
    how: fmf
execute:
    how: beakerlib

Test in main.fmf with content

test: ./runtest.sh
environment: {'BUNDLED_INJECT': 'PYTHONPATH=/usr/lib/python3.6/site-packages/pip/_vendor/',
 'PACKAGES': 'python3-pip',
 'PYTHON': 'python3'}

Execution as tmt run -d ends up with

   execute
        workdir: /var/tmp/tmt/run-055/repro/execute
        how: beakerlib
        Copy '/usr/lib/python3.7/site-packages/tmt/steps/execute/run.sh' to '/var/tmp/tmt/run-055/repro/execute'.

tests.yml from discover step has content

/one/repro:
    environment: BUNDLED_INJECT=PYTHONPATH=/usr/lib/python3.6/site-packages/pip/_vendor/
        PACKAGES=python3-pip PYTHON=python3
    path: /one/tests/repro
    test: ./runtest.sh

        Error: Unknown test variable:         PACKAGES=python3-pip PYTHON=python3

What this says is that run.sh can't parse it (it's read from tests.yaml file). It is caused by the simple yaml-like format data parser (it cannot read full yaml), and I'd rather avoid implementing it in bash, if possible.

What I'd recommend is to have the long line not-wrapped, which would simply make it work again. @psss, can we fix that on the generator / python side?

@lukaszachy is the dir intentionally nonexistent?

Yes, I was trying to create simpler reproducer.

Should be fixed by #188.
