* Remove tae types.

One type system for all.

Removed tae types.   Moved encoding into types to reduce a cyclic
dependencies.

Most the changes are like
find . -type f -exec sed -i 's/Type_BOOL/T_bool/g' {} \;

Some mock code in tae types are moved to container types. I don't think
those clock related actually belongs to types, but kept within types so
that the rest of the code refactoring is automatic.

* go fmt.

Previously, all Log Service requests and responses carry possible data fields as not nullable, meaning they are values rather than pointers. This would require full marshal/unmarshal of them even when they are empty. Changed them to pointer types to reduce such marshal and unmarshal overheads.

Log Service's ClientConfig and HAKeeper's HAKeeperClientConfig both have an optional DiscoveryAddress field which is the service address of a reverse proxy provided by k8s. The reverse proxy redirects requests to a random Log Service node and we use this mechanism to query Log Shard info from such random node. As such shard info is broadcasted to all Log Service nodes via gossip over time, this allows eventual discovery of the details of the interested Log Service shard.

This feature is required as replicas of a Log Shard can migrate to a completely different set of nodes over time, a pre determined & fixed address list alone won't be enough to allow clients to connect to the interested Log Shard.

* use constant connection timeout value which is much smaller than the LOG node heartbeat timeout. this ensures we get chance to try most specified HAKeeper nodes.
* during bootstrap, it is possible for the HAKeeper replica to be removed by a KILL command, terminate the local bootstrap procedure when that happens.
* always keep the ticker worker even after the HAKeeper replica is stopped.

When dns names are used in the GossipSeedAddresses field of logservice.Config, mo-service will try to resolve them and pass them to the logservice as a slice of strings in ip:port format. Only IPv4 addresses are kept and ErrInvalidConfig is returned if any dns name is mapped to more than one IPv4 address.
