* Doc fixes; tests for erroring if State is modified via API
* More review cleanup
* Uncomment tests!
* Minor suggested clean ups
* Change CA Configure struct to pass Datacenter through
* Remove connect/ca/plugin as we don't have immediate plans to use it.
We still intend to one day but there are likely to be several changes to the CA provider interface before we do so it's better to rebuild from history when we do that work properly.
* Rename PrimaryDC; fix endpoint in secondary DCs
* pass logger through to provider
* test for proper operation of NeedsLogger
* remove public testServer function
* Ooops actually set the logger in all the places we need it - CA config set wasn't and causing segfault
* Fix all the other places in tests where we set the logger
* Allow CA Providers to persist some state
* Update CA provider plugin interface
* Fix plugin stubs to match provider changes
* Update agent/connect/ca/provider.go

* Cleanup review comments
* add NeedsLogger to Provider interface
* implements NeedsLogger in default provider
* pass logger through to provider
* test for proper operation of NeedsLogger
* remove public testServer function
* Switch test to actually assert on logging output rather than reflection.

* Implement leader routine manager
Switch over the following to use it for go routine management:
• Config entry Replication
• ACL replication - tokens, policies, roles and legacy tokens
• ACL legacy token upgrade
• ACL token reaping
• Intention Replication
• Secondary CA Roots Watching
• CA Root Pruning
Also added the StopAll call into the Server Shutdown method to ensure all leader routines get killed off when shutting down.
This should be mostly unnecessary as `revokeLeadership` should manually stop each one but just in case we really want these to go away (eventually).
This fixes an issue where leaf certificates issued in secondary
datacenters would be reissued very frequently (every ~20 seconds)
because the logic meant to detect root rotation was errantly triggering
because a hash of the ultimate root (in the primary) was being compared
against a hash of the local intermediate root (in the secondary) and
always failing.
The fields in the certs are meant to hold the original binary
representation of this data, not some ascii-encoded version.
The only time we should be colon-hex-encoding fields is for display
purposes or marshaling through non-TLS mediums (like RPC).
* Store primaries root in secondary after intermediate signature
This ensures that the intermediate exists within the CA root stored in raft and not just in the CA provider state. This has the very nice benefit of actually outputting the intermediate cert within the ca roots HTTP/RPC endpoints.
This change means that if signing the intermediate fails it will not set the root within raft. So far I have not come up with a reason why that is bad. The secondary CA roots watch will pull the root again and go through all the motions. So as soon as getting an intermediate CA works the root will get set.
* Make TestAgentAntiEntropy_Check_DeferSync less flaky
I am not sure this is the full fix but it seems to help for me.
Secondary CA initialization steps are:
• Wait until the primary will be capable of signing intermediate certs. We use serf metadata to check the versions of servers in the primary which avoids needing a token like the previous implementation that used RPCs. We require at least one alive server in the primary and the all alive servers meet the version requirement.
• Initialize the secondary CA by getting the primary to sign an intermediate
When a primary dc is configured, if no existing CA is initialized and for whatever reason we cannot initialize a secondary CA the secondary DC will remain without a CA. As soon as it can it will initialize the secondary CA by pulling the primaries roots and getting the primary to sign an intermediate.
This also fixes a segfault that can happen during leadership revocation. There was a spot in the secondaryCARootsWatch that was getting the CA Provider and executing methods on it without nil checking. Under normal circumstances it wont be nil but during leadership revocation it gets nil'ed out. Therefore there is a period of time between closing the stop chan and when the go routine is actually stopped where it could read a nil provider and cause a segfault.
