Prevent storage manager creation during validate.

Instantiating an agent object creates an entry in the storage_managers table,
this is not the desired behavior when validating the storage manager's credentials.

Remove unused method VMDB::Config#schema_update
Remove @@ variables that can be accessed normally via VMDB::Config.new
Remove log.line_limit setting due to the inordinate complexity.

Managing line_limit requires a lot of code, which ultimately is never
used.  Developers lose information if the log lines are truncated, and
so in practice, and by default, it is disabled.  The line_limit setting
complicates things because the value is needed to initialize the logger,
which is initialized before access to the database is available, thus
managing changes and storing that change in the database creates a
chicken-and-egg problem.
