Feature: Generate Mocks Per Service

[rodneyosodo]

Is your feature request related to a problem? Please describe.

The problem we are currently having is that we write mocks for interfaces ourselves which might be cumbersome and had to maintain especially for SDK.

Describe the feature you are requesting, as well as the possible use case(s) for it.

Instead of writing down each mock for individual interfaces use https://github.com/vektra/mockery or https://github.com/uber-go/mock to generate mocks for interfaces. This will be instrumental in testing. This is quite useful for services depending on the SDK for example, bootstrap and certs service. This approach simplifies the testing process as initially, one would need to generate the things services, then the things server and finally use the things server URL on the SDK. This effective means that when testing other services you inherently test services that depend on the SDK which is not ideal. With SDK mocks you can mock the SDK rather than mocking dependent services.

Indicate the importance of this feature to you.

Due to the complexity of tests changes, we will update one service mock at a time. @nyagamunene @JeffMboya @arvindh123 Please comment here which services we need, and create issues out of that list. We must finish it by the end of S2.
