[Kernel] Proposal to change naming convention for getter method

[ebyhr]

Currently, kernel uses get prefix for getter method, but it will lead to inconsistent naming once we start using record of JDK 16.

I propose changing the convention to avoid get prefix as much as possible like Iceberg project.
https://iceberg.apache.org/contribute/#method-naming

2. Avoid get in method names, unless an object must be a Java bean.

• In most cases, replace get with a more specific verb that describes what is happening in the method, like find or fetch.
• If there isn't a more specific verb or the method is a getter, omit get because it isn't helpful to readers and makes method names longer.

Thanks, @ebyhr, for creating this issue. The proposed convention makes sense to me.

One qn I have is for the setX (for mutable objects). Is this remain the same or is there a convention?
