Issue #, if available:
fixes #451

• Adjusted order of how scheduling happens

  • First we determine if we have usable template (fail fast if not)

• If we have usable template, determine how we need to schedule

  • if Target is provided schedule on that node if template is there
  • if Target and allowedNodes missing assume we want all nodes to use in scheduling (discover all nodes)
  • if templates are on more nodes then is in allowedNodes schedule only on allowedNodes
  • if templates missing on some allowedNodes still continue to schedule on nodes where template exists.

LocalStorage:

• If localstorage (we have no easy way to determine if template is no localstorage):
  • multiple templates can be found
  • assign options.Node same as options.Target as we will use template from same node.
  • templateID and SourceNode cannot be used in this scenario
• If !localstorage
  • only 1 template can be found, if multiple found fail
  • schedule vm on any allowedNode (either Target or allowedNodes or discovered nodes)
  • templateID and SourceNode only can be used in this scenario

Fixed existing tests to reflect multiple scenarios (moving out templateID and SourceNode from setupReconcilerTest

• fixed yamlfmt

createVM had became too complex (gocyclo) as i've written in code for now it should be function to revisit and get into smaller chunks.
