Update most dependencies

[Marwes]

Just went through and updated most dependencies of sccache, mainly small cosmetic changes but I also used reqwest instead of hyper::Client in more places to be able to remove the explicit hyper-tls usage.

cargo outdated -R

Name     Project  Compat  Latest  Kind    Platform
----     -------  ------  ------  ----    --------
bincode  0.9.2    ---     1.0.1   Normal  ---
hyper    0.11.27  ---     0.12.8  Normal  ---

Avoided updating bincode since there maybe be versioning issues(?).

hyper-0.11 is also needed reqwest (no version has been release with hyper-0.12 yet) so I left it alone.

Thanks for the patch! This seems to be broken on Windows though, all the AppVeyor builds are busted:

error[E0432]: unresolved import `url`
  --> src\azure\blobstore.rs:25:5
   |
25 | use url::Url;
   |     ^^^ Did you mean `rouille::url`?
warning: unused import: `std::str::FromStr`

Note that Windows CI builds use --features="all-windows" which is "everything but gcs":

sccache/Cargo.toml

Line 108 in 55210fe

all-windows = ["redis", "s3", "memcached", "azure"]

Had to add the url feature for azure. Also updated winapi to 0.3.

I don't think this is a problem. sccache only uses bincode for communication between the client and server on the same machine, so they should always be the same version.

👍 Going through the rebase atm

Great, thanks! I started looking at this but it was sort of a PITA.

Rebased and updated rand and bincode as well

Thanks again! I should probably set up dependabot now that you've done most of the hard work. :)
