CORTX-29457: locale warnings generated as part of hctl command

[mssawant]

In container environment, locale -a command generates following warnings,

[root@cortx-data-headless-svc-ssc-vm-g2-rhev4-1630 /]# locale -a
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory

Hare hctl interface uses locale -a to find and set appropriate locale, thus the above warnings are generated during hctl command execution.

Solution: Redirect stderr messages generated on locale -a execution to /dev/null.
