* logger: missing https crate
* https: use RuntimeProvider when making connections
- [X] use RuntimeProvider when making TCP connections
- [ ] use RuntimeProvider when making TLS upgrades
- [ ] migrate tests
* RuntimeProvider::Tcp: remove async read/write
The TCP needs to Connect, the async readwriter will be in the
transport of connect. Thus we don't need it to be a requirement
on the top trait of RuntimeProvider
* AsyncResolver: remove async from new()
Related to overriding RuntimeProvider for #1074
Solves #1056
* cleanup tests
* rebase master for 0.19.5
* fix windows tests

1. Create a trait RuntimeProvider to abstract the resolver
implementation.
2. Make TokioAsyncResolver as default type.
3. Keep the tls related codes unchanged, which may be abstracted at a
later point.
4. Update the other codes and test cases wherever necessary.
