Java: kernel can evaluate if a custom/locked plan is applicable to ask if not generate a new plan

Need to have the ability to lock in a plan that is pre-defined by a developer. The plan can call plugins and prompts just like the dynamic plan that is returned by a planner.

When an ask is created from a user and comes into the kernel, the next step should be to look at the vector database to see if it can find a locked in place based on a description or ask set that the plan can achieve. If no plan can be found, then the next step is the normal flow of allowing a dynamic planner to process as normal.
,net issue microsoft/semantic-kernel#2314 for reference

首先追踪一个请求如何进入 kernel，以及 dynamic planner 如何被调用。检查向量数据库查询，以及对可以使用 plugins 和 prompts 的预定义计划的处理。完成的标准是选择一个适用的锁定计划，而没有该计划的请求则继续经过正常的动态规划流程。
