The lib name for the common components for writing packer_test suites was not clear, and did not follow the convention established in Packer core and plugins. Therefore this commit does two things: first the lib is renamed into common as to follow this convention, and clearly document which components are common to all tests. Also checkers are placed in a subpackage of common, common/check, so that it is clearer what is meant to be used as checks for a command's execution status after it's been run, as part of Assert.
