Should not use `com.github.timeplus`

[jovezhong]

The maven group id is com.github.timeplus today, the Java package is com.github.timeplus.jdbc

<dependency>
    <groupId>com.github.timeplus</groupId>
    <artifactId>timeplus-native-jdbc-shaded</artifactId>
    <version>..</version>
</dependency>

This is not appropriate. Similar to the proton JDBC driver

<dependency>
    <groupId>com.timeplus</groupId>
    <artifactId>proton-jdbc</artifactId>
    <version>0.6.0</version>
</dependency>

this package should be

<dependency>
    <groupId>com.timeplus</groupId>
    <artifactId>timeplus-native-jdbc</artifactId>
    <version>..</version>
</dependency>

Need to git mv the Java code and test code, as well as README/maven settings before we make it public

we will need replace com.github.timeplus with com.timeplus everywhere
