[FEATURE] Add multiple insert and delete functionality for in-memory cache

Feature Description

There are few cases where we insert/delete multiple keys in the cache. So add a function where it takes multiple key values and insert and delete it in the cache.

Possible Implementation

struct CacheValues {
	inner: Vec<String>
}

We can have a struct like this and make modify enum CacheKind to accept CacheValues.

enum CacheKind {
	Accounts(CacheValues),
	.....
}
