This PR addresses the overly broad permissions previously granted to the
AWS EBS CSI driver for managing 'leases'. It replaces the ClusterRole and
ClusterRoleBinding, which provided cluster-wide access, with a Role and
RoleBinding, limiting access to the namespace in which the driver is deployed.

What is this PR about? / Why do we need it?

The original configuration granted the driver access to leases across all
namespaces, which was unnecessary. By limiting access to the namespace in which the driver is deployed, we can enhance our security posture.

closes #1564

/lgtm

This commit modifies the driver's access to the 'leases' resource, restricting it to the namespace scope.

The previously used ClusterRole and ClusterRoleBinding have been replaced by a Role and RoleBinding to ensure the driver's permissions are limited to its containing namespace, aligning with security best practices.
