Noop text/plain formatter drops hyphens

[mfeit-internet2]

Found by accident:

The noop formatter removes hyphens from the keys in objects:

$ pscheduler task noop --data '{ "foo-bar": "baz-quux" }'

Not a problem with the raw result:

pscheduler result --format json  https://el9u-80q0sC0p/pscheduler/tasks/bdc73980-5e4e-436b-81c6-d327286cd15a/runs/0b39abd4-e17c-4723-a723-a2d594f4ddb0
{"data":{"foo-bar":"baz-quux"},"schema":1,"succeeded":true}

Hyphens were originally stripped because Jinja2 couldn't evaluate xxx.foo-bar. It can do xxx.get('foo-bar'), which solves that problem.

Removing all of the hyphen stripping and fixing all formatters to call get() when a value should have a hyphen.
