Remove page cache regular clear
Now the page cache is turned off by default. If the user manually opens the page cache, it can be considered that the user can accept the memory usage of the page cache, and then can consider adding a manual clear command to the cache.
fix memory gc cancel top memory query
jemalloc prof is not enabled by default
* Revert "[fix](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)"
This reverts commit 397cc011c4f1ba5a25c770258c13f1cd3f28b47d.
* [fix-resubmit](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)
ECB algorithm, block_encryption_mode does not take effect, it only takes effect when init vector is provided.
Solved: 192/256 supports calculation without init vector
For other algorithms, an error should be reported when there is no init vector
Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.

Note: This fix does not support smooth upgrades. during upgrade process, query may report error: funciton not found
Currently, if user modify the file on hdfs directly, no through hive. The changes of file will not be noticed by Doris and user
will get wrong data. Support the TTL(Time-to-Live) config of File Cache, so that the stale file info will be invalidated automatically after expiring.
1.Add a parameter configuration to set file cache ttl. "file.meta.cache.ttl-second".
2.Set the value corresponding to guava expireAfterAccess to the configuration value.

When using JDBC Catalog to query the Doris data, because Doris does not provide the cursor reading method (that is, fetchBatchSize is invalid), Doris will send the data to the client at one time, resulting in client OOM.
The MySQL protocol provides a stream reading method. Doris can use this method to avoid OOM. The requirements of using the stream method are setting fetchbatchsize = Integer.MIN_VALUE and setting ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY
1. add the global keyword.
SHOW [GLOBAL] [FULL] [BUILTIN] FUNCTIONS [IN|FROM db] [LIKE 'function_pattern']
SHOW CREATE GLOBAL FUNCTION function_name(arg_type [, ...]);
2. show the details of the global udf.
The information in the document is incomplete, user may be get error message like:
mysql> INSTALL PLUGIN FROM "http://127.0.0.1:8039/auditloader.zip";
ERROR 1105 (HY000): errCode = 2, detailMessage = http://127.0.0.1:8039/auditloader.zip.md5. you should set md5sum in plugin properties or provide a md5 URI to check plugin file
When setting FE config default_storage_medium to SSD, and set all BE storage path as SSD.
And table will be stored with storage medium SSD.
But there is a FE config storage_cooldown_second and its default value is 30 days.
So after 30 days, the storage medium of table will be changed to HDD, which is unexpected.
This PR removes the storage_cooldown_second, and use a max value to set the cooldown time of SSD
storage medium when the default_storage_medium is SSD.
Support create/drop global function.
When you create a custom function, it can only be used within in one database. It cannot be used in other database/catalog. When there are many databases/catalog, it needs to create function one by one.
## Problem summary
Describe your changes.
1、 When a function is created or deleted, add the global keyword.
CREATE [GLOBAL] [AGGREGATE] [ALIAS] FUNCTION function_name (arg_type [, ...]) [RETURNS ret_type] [INTERMEDIATE inter_type] [WITH PARAMETER(param [,...]) AS origin_function] [PROPERTIES ("key" = "value" [, ...]) ]
DROP [GLOBAL] FUNCTION function_name (arg_type [, ...])
2、A completely global global function is set, and the global function metadata is stored in the image. The function lookup strategy is to look in the database first, and if it can't be found, it looks in the global function.
