UTIL: Function 2string for enum sss_cli_command Improvement of debug messages. Instead of:"(0x0400): Running command [17]..." We could see:"(0x0400): Running command [17][SSS_NSS_GETPWNAM]..." (It's not used in sss_client. There are only hex numbers of commands.) Resolves: https://fedorahosted.org/sssd/ticket/2708 Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>
