fix: fix dynamic update config doesn't works for some param (#35572)

Browse Source 
issue: #35570
milvus support config cache to spped up config access, but only evict
param's cache when param has been updated. but milvus's param may rely
on other param's value, let's say ParamsA relys on paramsB, when paramsB
updated, it will evict paramB's cache, but the paramA's cache still keep
the old value.

This PR evict all config cache to solve the above issue, cause dynamic
update config won't be much frequetly.
