Download and Validate Image

File Path: "Artifacts_PATH/file_name" - ARTIFACTS_PATH points to /tmp

HTTPClient Unification

Now an agent receives an instantiated client which makes all the http requests.Currently it configured to be not validate the server certificate.Injecting the httpclient allows us to test out the api client.

@glimchb Should I remove this?

[glimchb]

@h0lyalg0rithm we have a separate issue for this #341 if you remove it it will fail CI/CD.. need to fix server certs

[glimchb]

should download go to utils ?

@h0lyalg0rithm

• refactor of HTTP client should be in a separate PR - too much changes to review at once
• I think we missing a point from the issue: if same running image - no need to download regardless if file is present or not... for example you run ubuntu 22.09 already, why would you want to download it again, unless --force flag given or something like this... wdyt ?

• ... for example you run ubuntu 22.09 already

Got it I assumed that if there are was an image present it would use it instead of downloading it.
I will move the httpclient change to a different PR
