testify mock linked in the final binary

**Describe the bug**

testify is a test dependencies and should not be used outside tests

The dependency is currently linked in the final binary.

I suspect this is caused by mocks being defined in non-test packages and in non-test files. The `github.com/stretchr/testify/mock.init` symbol is linked in the binary likely due to the import causing the call to the init method

**Preconditions**
Environment state and/or platform-specific configurations.

**To Reproduce**
Write the exact actions one should perform in order to reproduce the bug.
Steps to reproduce the behavior:
1. build cloudbeat
2. go version -m cloudbeat
3. observe testify in the dependency list

**Expected behavior**

testify is not included in the final binary
