Calc delete bitmap may generate segments, as a result, may trigger
segcompaction. But the BetaRowsetWriter is a transient one and in
Publishing context, which is bug-prone and hard to rollback. So let us
disable the triggering in delete bitmap calc code path.

1. Reduce the number of threads reading avro logs and keep the readers in a fixed thread pool.
2. Regularly cleaning the cached resolvers in the thread local map by reflection.
Sometimes, user may use a low version FE to read high version image, which may cause some undefined behavior
and hard to debug.

Sometimes, user need to add some custom libs to the cluster, such lzo.jar, orai18n.jar, etc.
In previous, these lib files are places in fe/lib or be/lib.
But when upgrading cluster, the lib dir will be replaced by new lib dir, so that all custom libs are lost.
In this PR, I add new dir custom_lib for FE and BE, and user can place custom lib files in it.
In some cloud native deployment scenario, BE(especially the Compute Node BE) will be add to cluster and remove from cluster very frequently. User's query will fail if there is a fragment is running on the shutting down BE. Users could use stop_be.sh --grace, then BE will wait all running queries to stop to avoiding running query failure, but if the waiting time exceed the limit, then be will exit directly. During this period, FE will not send any queries to BE and waiting for all running queries to stop
Create a jack user and set the password to expire after 10 days.
`CREATE USER 'jack' IDENTIFIED BY '12345' PASSWORD_EXPIRE INTERVAL 10 DAY FAILED_LOGIN_ATTEMPTS 3 PASSWORD_LOCK_TIME 1 DAY;`
After the password has expired, reset the password.
`SET PASSWORD FOR 'jack' = PASSWORD('123');`
Log in with a new password, ERROE ` Your password has expired. To log in you must change it using a client that supports expired passwords`
