when delegator has high memory usage, load l0 segment will failed. and
balance segment task will blocked by load segment task, then delegator
cann't free memory by moving out some segment, causes a logic dead lock.
this PR remove the limit for balance, we permit segment and balance
execute in parallel. which won't cause side effect due to:
1. one segment can only has one task in qc's scheduler, and load/release
task will replace balance task if necessary
2. balance speed has been limited, and it won't block load segment task.
3. if collection has load task and balance task at same time, load task
will be scheduled first due to high proirity.

This PR make `Trie` index using `MARISA_LABEL_ORDER`, which make
predictive search iterating in lexicographic order.
When trie index is build in label order, lexicographc could be utilized
accelerating `Range` operations.
However according to the official document, using `MARISA_LABEL_ORDER`
will make "exact match lookup, common prefix search, and predictive
search" slower.

There are serveral issue this PR addresses:
- Use `ResetTraceConfig` method instead init one in update event handler
- Implement dynamic stats.Handler to receive tracing config update event
- Update `enable_trace` flag when `ResetTraceConfig` is invoked
- Change `enable_trace` to `std::atomic<bool>` in case of data race

cause concurrent issue may occur between remove parition in target
manager and sync segment list to delegator. when it happens, some
segment may be released in delegator, and those segment may also be
synced to delegator, which cause delegator become unserviceable due to
lack of necessary segments, then search/query fails.
this PR make sure that all write access to target_manager will be
executed in serial to avoid the concurrent issues.

querycoord will notify proxy to update shard leader cache after
delegator location changes, but during querynode's failure recovery,
some delegator may become unserviceable due to lacking of segments, and
back to serviceable after segment loaded, so we also need to notify
proxy to invalidate shard leader cache when delegator serviceable state
changes.
This PR will maintain querynode's serviceable state during heartbeat,
and notify proxy to invalidate shard leader cache if serviceable state
changes.

In standalone mode, block the start process until the new coordinator is
active to avoid the coexistence of the old coordinator and the new
node/proxy
1. In the start/restart process, the new coordinator will become active
immediately and will not be blocked
2. In the rolling upgrade process, the new coordinator will not be
active until the old coordinator is down, and it will be blocked
