Support context propagation in the Swift storage integration

[FUSAKLA]

Is your proposal related to a problem?

The Swift storage integration is based on a library that does not support context propagation and allows just setting static timeouts currently. There is a standing issue on it to support the context. Once added there, Thanos should start using it also.

Issue on the used library ncw/swift#159

Created a PR to add context support to the library we use ncw/swift#162
