Misc cleanups, shellcheck warnings.
helmrepo.sh
-----------
o Use readarray -t to slurp command output.
o Replace while read -r with for loop iteration over named vars.
o Replace awk/string parsing with bash builtin string functions
(added insulation against external shell command failures).
o Added several functions to shorten all-code-in-main-program.
o Added functions func_echo() and error() for formatted output.
o Arguments --debug, --dry-run and --help added.
o 'helm package' command functions added to support --dry-run use.
o Detect and error on Chart.yaml files that lack 'version:'.
o chart_yaml_diff - differentiate no_diff case from error induced.
