Lifecycle expiration date, WithEndpoint, WithSSL issues cause functional tests to fail

[ebozduman]

Fixes the functional tests, part of the CI and merge process, failures.

The following issues are addressed :

• The life cycle expiration date is supposed to be replaced to the next day's midnight before the request is sent to the s3 server and the existing code was not doing it.
• WithSSl(secure=false) is ignored
• 3 versions of WithEndpoint() methods set endpoint either incorrectly and/or they were inconsistent
• BucketExistsAsync method exception handling and responseResult interpretation were not correct.

@tvdias and others,
Sorry for the mix up.
Not sure how the other commits (@tvdias and others) made into my PR.
I was reviewing and testing @tvdias PR #839 and I must have created this PR's branch on there instead of master.
Will be cleaning up those commits.

@ebozduman can you look at the tests?

[ebozduman]

Yes... already working on it.

My fix works in my local setup and all 6 bucket lifecycle tests pass.
In the build testing though, all but BucketLifecycleAsync_Test1.2 passes.
It looks like there is yet another problem still there and it is again another transient issue.
I'll be looking into this new problem.

Thank you.
