Improve HealthCheck command

[Darkangeel-hd]

This makes curl follow the redirect from http to https. Also disables SSL verification so that we can check the health if https is using some certs signed by a private, not trusted by default CA.

As this connects from the container to the container that shouldn't be a security issue (if someone's doing a MITM inside the container, we have worst problems to deal with)

The reason for the current health check is documented here: #39

Well I tried and i see no error popping up
the old wget command fails though

And the problem with the current curl command is that if http->https is on, it will just check that the server is responding
the server replies with a 307 Temporary Redirect
and curls stays there and never checks the actual reply of the https endpoint
-L/--location fixes that

and -k/--insecure makes it so that it trust the ssl connection

Another solution would be to reply for the health-checks on the http endpoint but that would require codebase changes

I am currently using the suggested change with no apparent issues.

So I don't really understand why it should stay like that

If you want me to try anything else pls let me know
And thank you in advance
