bump version to development v1.0.11
add mysql error 1267 (Illegal mix of collations) to invalid view detection logic
raise BackupError if exclude_invalid_views fails

- previously if a failing view was detected and MySQL raised
  an unknown error code, this method just reraised the original
  MySQLError.  This converts it to a more useful BackupError
  so holland does not raise an uncaught exception trace.
  If the invalid view handling fails still this probably means
  more error code classes need to be detected by holland.
Merge branch 'master' into feature/lp_1207852_improve_invalid_view_detection
add changelog entries for invalid view bugfixes (LP #1207852)

This notes that view errors that raise 1267 are now handled
and generally holland mysqldump now handles these errors
more gracefully.
detect rhel release better in scripts/mock_rpms.sh

Only check the first line of /etc/redhat-release for a version
string.
