This CL mainly changes:
1. Add a config to control the expire time of load job
Add a new FE config "streaming_label_keep_max_second" to control
the expire time of some high frequency load job such as INSERT and STREAM LOAD.
2. Remove expired txn in batch to avoid holding transaction lock for a long time
Currently Tablet meta checkpoint is a memory-exhausted operation.
If a host has 12 disks, it will start 12 threads to do tablet meta checkpoint.
In our experience, the data size of one tablet can be as high as 2G.
If 12 threads do the checkpoint at the same time, it maybe cause OOM.
Therefore, this PR try to solve this problem.
Firstly, it only start one thread to produce table meta checkpoint tasks.
Secondly, it creates a thread pool to handle these tasks.
You can configure the size of the thread pool to control the parallelism in case of OOM.
It is a producer-customer model.
Before drop a tablet, it will try to find the tablet in tablet map.
But the tablet maybe has been not existed.
Therefore, it is better to print the error message and error status.
Record finished stream load job (both successful job and failed job) into audit log
so that we can see when the stream load job was executed and check the details of stream load jobs.
* [Metrics] Add metrics to monitor BE's agent task queue size
Sometimes, user's DDL or background task may last a long time,
it's not easy to find out which procedure has problem.
This patch add metric to monitor BE's agent task queue size,
which would be helpful for troubleshooting.
The raw metrics on BE looks like:
doris_be_agent_task_queue_size{type="REPORT_OLAP_TABLE"} 0
doris_be_agent_task_queue_size{type="REPORT_DISK_STATE"} 0
doris_be_agent_task_queue_size{type="REPORT_TASK"} 0
doris_be_agent_task_queue_size{type="CHECK_CONSISTENCY"} 0
doris_be_agent_task_queue_size{type="DELETE"} 0

MemTracker can provide memory consumption for us to find out which
module consume more memory, but it's just a current value, this patch
add metrics for some large memory consumers, then we can find out
which module consume more memory in timeline, it would be useful to
troubleshoot OOM problems and optimize configs.
When replacing table with swap = false, the origin table's tablets
should be removed from tablet inverted index.

`BE`code can compile pass using `GCC 7.3.0`, but compiling `BE UT`code will encounter error using `GCC 7.3.0`. After upgrade gcc version to `10.2.1` which is the same version as in docker image, `BE UT` can be compiled successfully.
The old colocate join can only cover the case where the child is hash or scan.
In fact, as long as the child's data distribution meets the requirements,
no matter what the plan node on the child node is, a colocate join can be performed.
1. The MaterializedViewSelector should be reset for each scan node
2. On the BE side, columns with delete conditions must be added to the return column.
* [Enhance] Make MemTracker more accurate (#5515)
This PR main about:
1. Improve the readability of MemTrackers' name
2. Add the MemTracker of:
* Load
* Compaction
* SchemaChange
* StoragePageCache
* TabletManager
3. Change SchemaChange to a Singleon
* revise some code for Code Review
* change the name of mem_tracker
* keep reader_context have the same lifetime of rowset_reader in schema change.
* change vlog notice to log(warning) in schema change
