EISErr_RecvRespOutOfLimitsErr when AIS contains fullchain certificate

[Studio5086]

Expected Behavior

The AducIotAgent is able to retrieve a certificate from the AIS, even when its size is larger than 4096 bytes

Current Behavior

The AducIotAgent is failing to start with the error message:
Failed to provision a connection string from eis, Failed with error EISErr_RecvRespOutOfLimitsErr on service EISService_CertService [GetConnectionInfoFromIdentityService:561]

Steps to Reproduce

Provide a detailed set of steps to reproduce the bug.

1. Configure AIS to use a certificate longer than 4096 bytes. In this case the certificate is a full chain certificate which is being built by the AIS when using an EST server.

Device Information

• Custom Yocto Image
• Build AIS and iot-hub-device-update from source
