Bash integration script should namespace variables
In the original submitted script, it looks like there was effort put into namespacing all global variables. However a few mistakes remained. GLUSTER_TOP_SUBOPTIONSx were defined, but TOP_SUBOPTIONSx were referenced. This was likely an unrecognized defect in the original code submission? These are now corrected to refer to GLUSTER_TOP_SUBOPTIONSx. FINAL_LIST, LIST, and TOP were leaked into all Bash shells and used by the command completion functions. The most problematic of these was TOP, which was declared with "-i" making it an integer. This cause other code which used TOP to define a path to fail like this: $ bash $ TOP=/abc bash: /abc: syntax error: operand expected (error token is "/abc") These are now qualified as GLUSTER_FINAL_LIST, GLUSTER_LIST, and GLUSTER_TOP to reduce impact on scripts that might choose to use these extremely common variable names.
