refactor(deploymentmonitor): Configure SpinnakerRetrofitErrorHandler …

…for DeploymentMonitorService Update the error handler for the retrofit client, DeploymentMonitorService, to use SpinnakerRetrofitErrorHandler. Additionally, modify catch blocks with RetrofitError to use Spinnaker*Exception. Purpose : This commit is foundational work for upgrading the Retrofit version to retrofit2.x Behavioural change : The modification includes updating catch blocks, leading to a change in the format of logger messages. This aligns with the upcoming modifications discussed in the PR: #4608
