    Improve and fix syntax checks

    - Added some parameters to syntax check script in order to allow
      users to run tests against specific/all modules.
    - Fixed $GEM_HOME var, it should not be set script-wide, since it
      breaks test executed via puppet-lint utility. We should set
      $GEM_HOME only for 'bundle' commands.
    - Added possibility to disable 'rake lint' checks for modules with
      broken tests. Such modules will be tested with 'puppet-lint'
      utility.
    - Updated .puppet-lint.rc for Apache module to support older
      versions of puppet-lint.

    DocImpact: From now it's possible to run syntax check script for
    some specific modules using '--module PATH_TO_MODULE' option, or
    test all the modules at once using '--all'.
    If you want to disable 'rake lint' test for some module, please
    add such module name to './utils/jenkins/modules.disable_rake-lint'

    Fuel-CI: disable
