Put block list

• Implemented Put Block list
• Minor bugfix for Put Block
• Created IntoAzurePath trait

Ref pull request: #44

Partial implementation of block blob streaming access

• Implemented streaming block blob get with arbitrary chunk size.
• Added relative e2e test and example.

Ref issue: #42

0.7.0

• Removed azure module from all paths.
• Partial flattening of a few sub modules under cosmos (to be continued).
• Support for replace and delete document.
• Switch to ring for signing.
• Removed Deref and AsRef from API. It's bad practice: https://rust-lang-nursery.github.io/api-guidelines/predictability.html#only-smart-pointers-implement-deref-and-derefmut-c-deref.
• Few Cosmos' methods have been renamed.
• Added nyato to the list of the crate authors in Crates.io.

v0.6.1

• Removed unnecessary lifetime in impl Future return in storage.
• Removed unused lifetimes.
• Replaced try! with ? .
• Removes unused tokio dependency. PR #35 by nayato.
• Removed Cargo.lock by nayato.
• Update dependencies to state of the art (except future 0.2.x because ```Hyper`` does not support it yet).
• Fixed env_logger::init() because it no longer returns a Result.
• RustFmt'd with latest rustfmt-preview from rustup.

PartitionKey

Breaking changes:

• Changed most Cosmos document functions to accept a azure_sdk_for_rust::azure::cosmos::partition_key::PartitionKey instead of Option<Vec<&str>>. The former is just a more pleasant way of describing the same thing tough.

Other changes:

• Updated dependencies to latest Cargo version.

v0.5.0

• Changed all the remaining Box<Future> in impl Future
• Corrected a bug in lease blob: now we will pass 0 as Content-Length as required
• Rustformatted all the code
• Clipped code (many minor changes, mostly cosmetic ones)

Minor API change

Breaking changes:

• Removed Azure attributes from returned JSON (field QueryDocumentResponse<String>.results).

The removed attributes are in this slice:

const AZURE_KEYS: [&'static str; 5] = ["_attachments", "_etag", "_rid", "_self", "_ts"];

Cosmos document query methods implementation

Implemented features:

• Added Cosmos query document (both a plan JSON and DeserializeOwned implementing structs).
• Added more examples.

Replaced tuple return values with single struct for ergonomics

Breaking changes:

• Changed return type from tuple to single struct to make methods more ergonomic. Issue #26.

Type bugfix

Bugfixes

• Corrected a type mistake in multiple AsRef<str> parameters.
• Implemented AsRef<str> in Cosmos document and collection.
• Fixed type mismatch in examples (in README.md too).
