* Listener refactoring and file system permissions
* added listenerutil and move some common code there
* Added test for verifying socket file permissions
* Change default port of agent to 8200
* address review feedback
* Address review feedback
* Read socket options from listener config
* Implemented a warning when tls_cipher_suites includes only cipher suites which are not supprted by the HTTP/2 spec
* Added test for cipher suites
* Added hard fail on startup when all defined cipher suites are blacklisted. Added warning when some ciphers are blacklisted.
* Replaced hard failure with warning. Removed bad cipher util function and replaced it by external library.
* Added missing dependency. Fixed renaming of package name.
* Port over OSS cluster port refactor components
* Start forwarding
* Cleanup a bit
* Fix copy error
* Return error from perf standby creation
* Add some more comments
* Fix copy/paste error
* initial commit for prometheus and sys/metrics support
* Throw an error if prometheusRetentionTime is 0,add prometheus in devmode
* return when format=prometheus is used and prom is disable
* parse prometheus_retention_time from string instead of int
* Initialize config.Telemetry if nil
* address PR issues
* add sys/metrics framework.Path in a factory
* Apply requiredMountTable entries's MountConfig to existing core table
* address pr comments
* enable prometheus sink by default
* Move Metric-related code in a separate metricsutil helper
* Two things:
* Change how we populate and clear leader UUID. This fixes a case where
if a standby disconnects from an active node and reconnects, without the
active node restarting, the UUID doesn't change so triggers on a new
active node don't get run.
* Add a bunch of test helpers and minor updates to things.
* Make useCache explicit everywhere in lock manager
This also clears up a case where we could insert into the cache when it
wasn't active
* Address feedback
The result will still pass gofmtcheck and won't trigger additional
changes if someone isn't using goimports, but it will avoid the
piecemeal imports changes we've been seeing.
