Allow wildcard host assignment with sql.

[razorsedge]

Since mysql:db requires class mysql::server, we assume to run all commands as the root mysql user against the local mysql server. Therefore, Exec["${name}-import"] can be simplified and will also succeed with the following wildcard host assignment:

mysql::db { 'mydb':
  user     => 'myuser',
  password => 'mypass',
  host     => '%',
  grant    => ['all'],
  sql      => '/path/to/file.sql',
}

This time with no formatting "fixes".
