[LU-9153] improve FID/config name specification for lctl llog_print and llog_info

• Type: Improvement
• Resolution: Fixed

Description

Current llog name specification is totally non-standard for lctl llog_print, llog_info, and related commands. Change this to optionally accept config llog names without the leading '$', since adding '$' is non-intuitive and the shell will think this is a variable and "$fsname-client" becomes "-client".

Similarly, llog identifiers are formatted like "#0x4:10#0000000" instead of the standard FID format [0x4:0x10:0x0]. Update the code to print FIDs in standard format.
