Changes

• ValidateInstanceInContext split into maya and nuke plugin
  • added settings for each of them
• context anatomy collector also stores task type of context
• start/stop timer plugins are using settings stored in context instead of loading them again
• ValidateIntent is for all hosts by default and added profiles to filter validations (by default is plugin disabled)
• ValidateVersion added active attribute to be able define if is activated by default

QUESTIONS

• ValidateContainers - currently has settings in each host settings and not sure if should be added to global publish plugins settings and if yes than it will probably need profiles but at the same time should have optional (maybe) does it make sense to have both optional + active and profiles under that?
• ValidateResources I actually don't know why are resources validated? is required does not need settings
