* Move configuration from lib/service to lib/service/servicecfg
The new servicecfg package will hold only configuration for services.
This will allow other packages (like tctl and tsh) to depend on
servicecfg without pulling in all of lib/service (which has a number
of platform-specific details).
This is the first step towards being able to build tctl for Windows.
* Move PAM and BPF config into servicecfg
This breaks a compile-time dependency on BPF/PAM for tctl.
* Add x-teleport-api-error to reserved headers
* Update app tests for rewritten headers
* Add test case for x-teleport-api-error
* Fix test for XForwardedSsl since it was effectively untested before
* Refactor leaf test to parse the response from dumper app
* Update docs reference reserved headers
The "tets bundling" introduced in TesAppAccess() made TestAppInvalidateAppSessionsOnLogout test very unstable as other tests are modifying the state of the whole suit.
Removing the test from the bundle seems to fix it.
The TestTCPCertExpiration test may have a race condition where the connection
made to the test application immediately after the cert expiry may succeed.
Due to the wonky nature of using the fake clock in this test, I'm introducing
a requires.Eventually here to hopefully mitigate this race.
The CertificateTTL causes problems after the introduction of the fake clock
into the appaccess tests due to the fake clock not being propagated properly
throughout the Teleport stack. Increasing the TTL should make this test much
less flaky.
The appaccess TestTCP* tests are highly reliant on time. This has been
reduced (but not eliminated) by using a fakeClock and a channel for
signaling monitor triggered connection closures.
Application access connection monitoring has been introduced so that, when a
lock is created, application access connections will be interrupted until the
lock has been cleared. This includes web sockets and TCP applications.
Application sessions were previously only logged when launching an application
session via the UI, and not from the `tsh app login` command. This has been
corrected. The AppName and AppURI are now passed in as part of the gRPC
request to the auth server, which is then used to emit the audit event.
