[FEATURE] : add pagination support for customers list · juspay/hyperswitch#3746

### Feature Description The [customers list](https://github.com/juspay/hyperswitch/blob/4ae28e48cd73a9f96b6ae24babf167824fd182a0/crates/router/src/routes/customers.rs#L68) endpoint currently has no pagination support. It returns the list of all the customers in the database. There would be thousands of customers for a merchant. A pagination support for the api would be necessary. ### Possible Implementation accept two fields, `limit` and `offset` - `limit` specifies the number of objects returned in the response. - `offset` specifies the number of items to skip from the start, this is open to discussion whether to use offset or some other field. This would be similar to the `payments_list` pagination.

Feature Description

The customers list endpoint currently has no pagination support. It returns the list of all the customers in the database. There would be thousands of customers for a merchant. A pagination support for the api would be necessary.

Possible Implementation

limit specifies the number of objects returned in the response.
offset specifies the number of items to skip from the start, this is open to discussion whether to use offset or some other field.

This would be similar to the payments_list pagination. Refer here
