Enhance logger to format message with placeholders

[odain-cbd]

After struggling with a CSV collector that had hidden hideous '\uFEFF' invible char in header line, I decided to propose below enhancements (I could have spared so much time and energy)

• enhancing logging mechanism with placeholders
  Example:
  Utils::Log(LOG_WARNING, "Invalid columns '%1\$s' '%2\$s' '%3\$s'.", "primary_key", "colA", "colB");

• using this new behaviour in some collect/synchro strategical places to help collector users detects special chars issues.

Example: use a CSV collector with below line
\uFEFFprimary_key,name,lastname,whatever 123,john,does,yes

Output TODAY:
[WARNING] Invalid column 'primary_key', will be ignored. [ERROR] Failed to import the data

Output with PR:
[WARNING] Invalid column '\uFEFFprimary_key', will be ignored. [ERROR] Failed to import the data

I simple used sprintf before, but I'm fine with this as well..
