Introducing the #vase/conform action

[mtnygard]

• Accesses data from the context map.
• Use the :from setting to define which context map value is interesting.
• The :spec key identifies which spec the data should conform to
• Conformed data will be reattached to the context map under the :to key
• If conform fails, the explain-data is attached to the context map.
• By default, explain-data gets attaches as :com.cognitect.pedestal.vase.actions/explain-data.
• You can override that with the :explain-to key.
