additionalTrustBundles property
Maps specific trust domains (e.g., "example.com") to their corresponding TrustStore, which contain the trusted root certificates for that domain.
There can be a maximum of 10 trust domain entries in this map. Note that a trust domain automatically trusts itself and don't need to be specified here. If however, this WorkloadIdentityPool's trust domain contains any trust anchors in the additional_trust_bundles map, those trust anchors will be appended to the trust bundle automatically derived from your InlineCertificateIssuanceConfig's ca_pools.
Optional.
Implementation
