Add support of EXPIRETIME and PEXPIRETIME

[kay011]

This commit finish the #1948 and #1947.
It should be noted that since the timeout precision currently supported by kvrocks is seconds, the results obtained by executing PEXPIRETIME will be different from those obtained by redis. This is my first time trying to implement a kvrocks command, please give me your code review comments. Thanks!

Thanks for your effort!

If you build kvrocks with -DENABLE_NEW_ENCODING=ON, you can see that the precision of these expire time is in milliseconds.
