[Enhancement]: Support only-sealed load operation for Milvus

[chyezh]

Is there an existing issue for this?

• I have searched the existing issues

What would you like to be added?

Currently, milvus load operation will always load the growing segment.
But in some scene, User only want to load the sealed segment, and only search the sealed segment.
So we need to support a new load option to ask milvus only load sealed segment.

Why is this needed?

Anything else?

so load have multiple types? active, lazy and historical load?

From my understanding, the load option is orthogonal to options such as lazy.
User can use lazy and historical together, is it? @liliu-z

yes, it's just another different mode, we can multiple mode together
