update dependencies: reqwest

[Mina Galić]

reqwest is now available in version 0.10.
This brings in a whole slew of new updates up the chain:

tokio v0.1.22
├── hyper v0.12.35
│   ├── hyper-tls v0.3.2
│   │   └── reqwest v0.9.24
│   │       ├── webfinger v0.4.1

vs

tokio v0.2.10
├── h2 v0.2.1
│   └── hyper v0.13.1
│       ├── hyper-tls v0.4.1
│       │   └── reqwest v0.10.1

another advantage of this upgrade, we can chose to use rustls as our tls library of choice, thus reducing dependence on openssl!

[Mina Galić]

should release this as an in-between step before #11?

[Ana Gelez]

I don't think so, we can make a release with both changes.

[Mina Galić]

aye. thanks for weighing in.
