Mistral allows creating workflows with spaces in name but could not work with it

[Artem Lapin]

We can create workflows definition with spaces in name, for example:

version: '2.0'
wf1:
  tasks:
    t1:
      workflow: name with spaces
name with spaces:
   tasks:
     t2:
       action: std.noop

But if we try to execute workflow "wf1" we get error, because Mistral tries to find subworkflow "name" instead of "name wit spaces", because Mistral defines "with spaces" as parameters for subworkflow "name". I propose prohibit the creation of workflow with spaces in the name.
