Add HttpWaitStrategy

Impl for #236

I originally build this for Req. Then saw, there is Tesla. I followed their docs to build the client and make a request - I never used tesla before. I checked the response type from tesla and req and they are pretty equal for the response.

While I tested this with Req, this PR is completely untested - but I thought it's good enough to say hello :)

looks useful :) should be very easy to test it in a isolated manner outside a container configuration. Just start a container with the exunit macro and then construct and call the strategy ? then another test would be to create a special container, maybe an nginx container, that serves a specific html file or something. However it seems to always take a map in the match function. Is it a requirement as the strategy is now that response must be json ? Should it require that?

I did a test-case, verifying the default index.html file from nginx is up.

I don't think at all. You are free to pass headers and a matcher to adjust to your setting.

And I hit a timeout on CI. Quite ironic, it is a :socket_closed_remotely error, addressing that is the reason for this PR 😅

But apparently this is a layer lower - any idea for this?

being so random, i try to run them again. they told me nothing. It could be the engine, testcontainers calling the strategy, but meh .. i will think about it
