Fix work load group GC, add cancel load and add logs.
Unify the format and change all to lowercase of GC logs, avoid unnecessary trouble when grep or less
Add logs to help locate the cause of slow GC.
Current initialization dependency:
Daemon ───┬──► StorageEngine ──► ExecEnv ──► Disk/Mem/CpuInfo
│
│
BackendService ─┘
However, original code incorrectly initialize Daemon before StorageEngine.
This PR also stop and join threads of daemon services in their dtor, to ensure Daemon services release resources in reverse order of initialization via RAII.
Memtrackers are usually bound to operators in query/load. If a large number of query/loads are stuck, memtrackers will be very large. memory tracker profile refresh thread will get stuck on the lock.
This pr is for branch-2.0, I will rewrite the memory profile in the next pr
Jemalloc dirty page only use madvise MADV_FREE, memory is not release back to system, RSS won't reduce in time,
So when the process memory exceed limit or system available memory is insufficient,
manually transfer dirty page to the muzzy page, which will call MADV_DONTNEED to release the physical memory back to the system.

Only switch to bthread local when modifying the mem tracker in the thread context. No longer switches to bthread local by default when bthread starts
mem tracker increases brpc IOBufBlockMemory memory
remove thread mem tracker metrics
After the query check process memory exceed limit in Allocator, it will wait up to 5s.
Before, Allocator will not check whether the query is canceled while waiting for memory, this causes the query to not end quickly.
fix mem_limit default value
memory_gc_sleep_time_s to memory_gc_sleep_time_ms
LoadChannelMgr::_handle_mem_exceed_limit process_mem_limit to process soft mem limit
fix query mem tracker print
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.

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
Fix MacOS mem_limit parse result is 0.
Fix GC after env Init, otherwise, when the memory is insufficient, BE will start failure.

Add a special counter for memtracker, faster, but relaxed ordering and not accurate in real time
Track thread create and destroy memory, which was previously removed due to performance loss and added back
Fix Redhat 4.x OS /proc/meminfo has no MemAvailable, disable MemAvailable to control memory.
vm_rss_str and mem_available_str recorded when gc is triggered, to avoid memory changes during gc and cause inaccurate logs.
join probe catch bad_alloc, this may alloc 64G memory at a time, avoid OOM.
Modify document doris_be_all_segments_num and doris_be_all_rowsets_num names.
Support IPV6 in Apache Doris, the main changes are:
1. enable binding to IPV6 address if network priority in config file contains an IPV6 CIDR string
2. BRPC and HTTP support binding to IPV6 address
3. BRPC and HTTP support visiting IPV6 Services
MetricRegistry::trigger_all_hooks holds the metrics lock and is stuck in get_je_metrics, to_prometheus is waiting for MetricRegistry::trigger_all_hooks to release the lock, so get_je_metrics is no longer called in MetricRegistry::trigger_all_hooks.
1. When the process memory is insufficient, print the process memory statistics in a more timely and detailed manner.
2. Support regular GC cache, currently only page cache and chunk allocator are included, because many people reported that the memory does not drop after the query ends.
3. Reduce system available memory warning water mark to reduce memory waste
4. Optimize soft mem limit logging
if we set enable_system_metrics to false, we will see be down with following message "enable metric calculator failed,
maybe you set enable_system_metrics to false ", so fix it

When the system MemAvailable is less than the warning water mark, or the memory used by the BE process exceeds the mem soft limit, run minor gc and try to release cache.
When the MemAvailable of the system is less than the low water mark, or the memory used by the BE process exceeds the mem limit, run fucc gc, try to release the cache, and start canceling from the query with the largest memory usage until the memory of mem_limit * 20% is released.
