issue: #32995
To speed up the construction and querying of Bloom filters, we chose a
blocked Bloom filter instead of a basic Bloom filter implementation.
WARN: This PR is compatible with old version bf impl, but if fall back
to old milvus version, it may causes bloom filter deserialize failed.
In single Bloom filter test cases with a capacity of 1,000,000 and a
false positive rate (FPR) of 0.001, the blocked Bloom filter is 5 times
faster than the basic Bloom filter in both querying and construction, at
the cost of a 30% increase in memory usage.
- Block BF construct time {"time": "54.128131ms"}
- Block BF size {"size": 3021578}
- Block BF Test cost {"time": "55.407352ms"}
- Basic BF construct time {"time": "210.262183ms"}
- Basic BF size {"size": 2396308}
- Basic BF Test cost {"time": "192.596229ms"}
In multi Bloom filter test cases with a capacity of 100,000, an FPR of
0.001, and 100 Bloom filters, we reuse the primary key locations for all
Bloom filters to avoid repeated hash computations. As a result, the
blocked Bloom filter is also 5 times faster than the basic Bloom filter
in querying.
- Block BF TestLocation cost {"time": "529.97183ms"}
- Basic BF TestLocation cost {"time": "3.197430181s"}

YAML will automatically parse "off" as a boolean variable. We should
avoid using "off" in the future.

This PR introduce two database level props:
1. database.replica.number
2. database.resource_groups
User can set those two database props by AlterDatabase API, then can
load collection without specified replica_num and resource groups. then
it will use database level load param when try to load collections.

`LocationCache` used map to store different locations for different K
which may cause lots of CPU time when get locations many times.
This PR change the implementation of LocationCache to store only the
location for the largest K used to totally remove the map access
operation.

There were some frequent scan in metacache:
- List all segments whose start positions not synced
- List compacted segments
Those scan shall cause lots of CPU time when flushed segment number is
large meanwhile `Flushed` segments can be skipped in those two scenarios
This PR make:
- Add segment state shortcut in metacache
- List start positions state before `Flushed`
- Make compacted segments state to be `Dropped` and use `Dropped` state
while scanning them

pr #32814 introduce the compatible issue, when upgrade to milvus latest,
the query coord may skip update dist due to the lastModifyTs doesn't
changes. but for old version querynode, the lastModifyTs in
GetDataDistritbuionResponse is always 0, which makes qc skip update
dist. then qc will keep retry the task to watch channel again and again.
this PR add compatible with old version querynode, when lastModifyTs is
0, qc will update it's data distribution.

disabled due to https://github.com/milvus-io/milvus/issues/32214.
In restful api, the accepted json formats of sparse float vector are:
* `{"indices": [1, 100, 1000], "values": [0.1, 0.2, 0.3]}`
* {"1": 0.1, "100": 0.2, "1000": 0.3}
