* utils: fix IPv6 address w/ port parsing
This was using a deprecated function (`urllib.splitnport`),
ostensibly to work around issues with brackets on IPv6 addresses.
Ironically, its usage was broken, and would result in mangled IPv6
addresses if they had a port specified in some instances.
Usage of the deprecated function has been eliminated and extra test
cases added where missing. All existing cases pass as-is. (The only
other change to the test was to improve assertion messages.)

* tls: use auto-negotiated highest version
Specific TLS versions are deprecated in latest Python, which
causes test failures due to treating deprecation errors as
warnings.
Luckily, the fix here is straightforward: we can eliminate some
custom version selection logic by using `PROTOCOL_TLS_CLIENT`,
which is the recommended method and will select the highest TLS
version supported by both client and server.

* ssh: reject unknown host keys when using Python SSH impl
In the Secure Shell (SSH) protocol, host keys are used to verify the identity of remote hosts. Accepting unknown host keys may leave the connection open to man-in-the-middle attacks.
Do not accept unknown host keys. In particular, do not set the default missing host key policy for the Paramiko library to either AutoAddPolicy or WarningPolicy. Both of these policies continue even when the host key is unknown. The default setting of RejectPolicy is secure because it throws an exception when it encounters an unknown host key.
Reference: https://cwe.mitre.org/data/definitions/295.html
NOTE: This only affects SSH connections using the native Python SSH implementation (Paramiko), when `use_ssh_client=False` (default). If using the system SSH client (`use_ssh_client=True`), the host configuration
(e.g. `~/.ssh/config`) will apply.
