Global cache expiration period

## Description

I want to set all cache items expiration globally in my project, but not pass the expiry in the `Set` or `Get` methods

### Related code

```csharp
_inMemoryCaching.Set("SomeKey", "SomeValue");
```
Instead of
```csharp
_inMemoryCaching.Set("SomeKey", "SomeValue", TimeSpan.FromMinutes(5));
```
the same for `Get`

**Expected behavior:** Get the expiry from EasyCaching configs

**Actual behavior:** There is no way to get the global expiration period from congfis
