return object if mapped as create_entity does
extent recognizing of already existing objects

organization: /has already been taken/
user: /already exists/
host-collection: /must be unique within one organization/
product: Product with name '<name>' already exists in this organization
repository: /has already been taken for this product./
content-view: /has already been taken/
activation-key: /has already been taken/
template-snippet: /has already been taken/
catch exceptions when deleting system content views
add template snippet import to simple test
1135588 - Teach config-file to reuse credentials from @api
rubocop: lib/hammer_cli_import/base.rb:345:5: C: Cyclomatic complexity for create_entity is too high. [20/11]

1133846 - Teach config-file the diff between 'created' and 'wrote'
  - Summary now recognizes :wrote and :failed
  - configfile summarizes filesystem ops as :wrote
  - configfile.rb checks for hammer-invocation-failure
  - tripped over/fixed a bug in rcop fix from prev commit
add the innocent line lost by refactoring
do not count unavailable entities as :found when deleting
catch sat6 delete exception and count them into summary
