//
// # API Overview
//
// Certificates Manager API allows customers to see and manage all their TLS
// certificates.
//
// Certificates Manager API service provides methods to manage certificates,
// group them into collections, and create serving configuration that can be
// easily applied to other Cloud resources e.g. Target Proxies.
//
// # Data Model
//
// The Certificates Manager service exposes the following resources:
//
//	Certificate that describes a single TLS certificate.
//
//	CertificateMap that describes a collection of certificates that can be
//	attached to a target resource.
//
//	CertificateMapEntry that describes a single configuration entry that
//	consists of a SNI and a group of certificates. It’s a subresource of
//	CertificateMap.
//
// Certificate, CertificateMap and CertificateMapEntry IDs
// have to fully match the regexp [a-z0-9-]{1,63}. In other words,
//
//	only lower case letters, digits, and hyphen are allowed
//
//	length of the resource ID has to be in [1,63] range.
//
// Provides methods to manage Cloud Certificate Manager entities.
