Find suitable replacements for LC modules

[piojo-zz]

LC is not maintained anymore. Lionel has suggested us to move from it and use No::Worries (in CPAN, RPMs available in EPEL for EL5+). At this time we should start looking for alternatives on each of the tasks LC modules perform for us.

Over the top of my head, CAF consumes:

• Process
• File::status
• Syslog

Plus there are usages of copy and makedir. And Exceptions are cumbersome to use.

Suggestion is to open a separate issue to discuss replacement of each of perl-LC submodule used by Quattor to a avoid a long and messy discussion here. Every sub-issue must reference this one.
