Adds a method to resources MatchSearch, that goes through
select resource field values, and matches it against a list of
user provided search values.
Part of RFD 55
- Ensure that the dial request uses proper "server ID" format,
which is <uuid>.<cluster_name>
- Update reverse tunnel agent to handle tunnel connections
to desktops
This patch will allow the web api to (optionally) fall back from HTTPS
to HTTP under very particular circumstances:
1. The appropriate `insecure` flag was set, and
2. The target host is the loopback
If both conditions are met, this patch will allow the WebAPI client to
fall back to plain HTTP when attempting to login to the auth server.
Load access requests from SSH cert instead of the profile. The profile
only exists on CLI clients, but not in the proxy.
Note: theoretically, SSH cert may be missing in some cases for CLI
clients. We should eventually encode access requests in TLS certs too,
which are always present.
By specifying `device_attestation_cas` in `teleport.yaml`, admins can
restrict U2F device manufacturers. For example, specifying the yubico
attestation CA
(https://developers.yubico.com/U2F/yubico-u2f-ca-certs.txt), you can
restrict users to only yubikeys.
Example error when using the yubico CA and trying to register a Google
Titan key:
```
$ tsh mfa add --type u2f --name test && tsh mfa rm test
Tap any *registered* security key
Tap your *new* security key
ERROR: rpc error: code = InvalidArgument desc = U2F device attestation certificate is signed by "CN=Security Key,O=Google", but this cluster only accepts certificates from ["CN=Yubico U2F Root CA Serial 457200631"]; make sure you're using a U2F device from a trusted manufacturer
```
* Added support for connecting API client through tunnel proxy and web proxy addresses (with identity file).
* Added concurrent dialing logic to dial several possible dialing combinations and seamlessly return the first client to connect.
