Support quote on the output field

[lowell80]

Support a command like this:

sourcetype="ms:o365:management AzureActiveDirectory | jmespath output="Actor.Type[*]" "unroll(Actor, 'Type', 'ID')"

Right now this works, but it creates a field with double quotes around it. DOH! We also want to be able to support fields that could contain a whitespace character (event though that's bad form).

The current workaround is follow this up with an extra rename operation, which shouldn't be necessary.

See if #9 solves this.

Still broken in 1.9.5:

| jmespath output="inquiry_type" "fields[?title=='Inquiry Type'].value"

Produces the field "inquiry_type" (with quotes)
