[seata]seata client sdk无法使用opengauss驱动创建本地数据库连接

目前使用1.4.2或者1.7.0客户端sdk与springboot集成使用时，数据库驱动使用opengauss连接，数据库为南大通用8C，发现应用启动时，提示nullpoint exception，查看异常位置是seata通过数据源url解析dbtype时，调用了druid包的JdbcUtils的getDbTypeRaw接口返回null值，但是查看getDbTypeRaw方法只有当入参rawUrl为null时，才会返回null。

============================= 异常信息： Caused by: java.lang.NullPointerException: null at io.seata.rm.datasource.util.JdbcUtils.getDbType(JdbcUtils.java:54) at io.seata.rm.datasource.DataSourceProxy.init(DataSourceProxy.java:89) at io.seata.rm.datasource.DataSourceProxy.(DataSourceProxy.java:82) at io.seata.rm.datasource.DataSourceProxy.(DataSourceProxy.java:67) at io.seata.spring.annotation.datasource.SeataAutoDataSourceProxyCreator.buildProxy(SeataAutoDataSourceProxyCreator.java:125) at io.seata.spring.annotation.datasource.SeataAutoDataSourceProxyCreator.wrapIfNecessary(SeataAutoDataSourceProxyCreator.java:99) at org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator.postProcessAfterInitialization(AbstractAutoProxyCreator.java:300) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization(AbstractAutowireCapableBeanFactory.java:430) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1803) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:594)
