marklogic:install-cpf phase fails if CPF domain already exists

[ellispritchard]

The plugin fails if a CPF domain configured in the content-processing section already exists; this is because the underlying MarkLogic cpf/domains.xqy create() function fails if the domain exists, and there is no handling of this in the marklogic-install-server module code:
