the bash_it recipe's default custom plugins are not easily overridable

[codeword]

the bash_it recipe looks for custom plugins in the attributes node bash_it -> custom_plugins and defines a default set as

custom_plugins:
  sprout-base:
    - pluginA
    - pluginB

but chef only overrides defaults at the leaf nodes, so in soloist

custom_plugins:
  my-plugins:
    - pluginC

results in pluginA, pluginB and pluginC all being installed.

If a user doesn't want pluginA or pluginB installed they would need to set sprout-base to an empty array.

custom_plugins:
  my-plugins:
    - my-plugin
  sprout-base: []

which is very surprising behavior.
