LU-930 doc: fix format man page sections for lctl

For lctl man pages, add proper formatting for the NAME
and TITLE sections so that 'man -k lctl*' reports the
real explanation for the command/utility and not
"(unknown subject)".

Modifications in this patch include:
- add a dash between multi-word name commands in NAME
- format the date to YYYY-MM-DD in TITLE
- capitalize command in TITLE
- change hyphen (-) to underscore in command where necessary
