* Implement Schemar.SetDatabaseOption(option, value string) This replaces the temporary `SetDatabaseOptions()` method, which replaced the entire DatabaseOptions struct, with `SetDatabaseOption` which takes an option/value pair of strings to set. * Add SetDatabaseOption to controller http handler and client This commit also: - renames some `writeLog` to `writelog` - updates ApplyDirective to call resource.Unlock() on any resources being removed from the local worker * Add Database related methods to SchemaAPI interface Currently all implementations of this interface are implemented with "unimplemented" errors on those methods. Next will be to implement the necessary methods. * SQL: CREATE DATABASE and SHOW DATABASES * SQL: DROP DATABASE * SQL: Add UNITS option to CREATE DATABASE * SQL: ALTER DATABASE * User serverlessStorage.Remove[*]Resource instead of resource.Unlock() * Add WITH keyword to CREATE/ALTER DATABASE * fix some WITH logic * linter fixes * WITH on CREATE DATABASE is not required
