As a developer I want integration and E2E-tests for Chirp.CLI.Clients interactions with the web service

[torbjornjohannsen]

Note: This should NOT access the actual production server, but rather mock it via a locally hosted instance(where we can arrange the data to be whatever we want as well)

Acceptance Criteria:

• E2E test for cheeping, ie inputting a message into the client that then gets stored in the database of the service
• E2E test for reading, ie asking the client to read and it properly retrieving the cheeps from the service
• Integration test for storing JSON-formatted data in the database via the web service(Should be at the detail level of mocking a HTTP-post request and and validating the database)
• Integration test for retrieving JSON-formatted data from the database via the web service(Likewise at the detail level of mocking a HTTP-get request and validating the response)
