HAWQ-77. Fix source code comment for new ALTER/CREATE RESOURCE QUEUE ddl 
statements
    Fix contains:
    1. start error message with a lowercase letter
    2. avoid contractions in error message
    3. refine "can not" to "cannot"
    4. add single quote to resource queue name
    5. remove unused function "getLocalTmpDirFromMasterRM"
