Uberproxy actively kills long standing connections after a set period of
time. This change adds a 30 second keep alive period for SSE connections
so connections can be reestablished after being killed by Uberproxy
without DDS assuming the connection has disappeared.

Added tests to try and emulate failures reported in flutter_tools crash
reports. Used these tests to update error handling and get a better
understanding of exception scenarios.

Changes DDS from invoking the VM's private compilation RPCs directly
when an external compilation service is not present. This resulted in
expression evaluation failing when the VM Service implementation was
DWDS.

Fixes situation where confusing errors were thrown when DDS was shut
down while starting up (e.g., StateError from in-flight requests,
WebSocket exceptions due to the VM service disappearing, etc).

The VM service sends ServiceRegistered events for each registered
service to each client when they first subscribe to the Service stream.
DDS was not mimicking this behavior correctly.

In https://github.com/dart-lang/json_rpc_2/pull/52 the `Peer` class was
fixed to behave like a `Client` when the connection is closed with
outstanding requests.
`package:dds` was previously relying on having the futures never
complete to send the `serviceDisappeared` code when the client was
closed with outstanding requests. Check also for the `StateError` that
would result from outstanding requests and translate them to
`serviceDisappeared`.

Final cleanup work before first full version of package:dds is
published:
- Added `getSupportedProtocols` RPC to the VM service protocol, which returns a
list of supported service protocols and extensions along with their version
information.
- Added `getDartDevelopmentServiceVersion` RPC to the DDS protocol.
- Misc code and dependency cleanup recommended by pub

Added the following RPCs to the DDS protocol:
- getLogHistoryLength
- setLogHistoryLength
Historical logs will be sent to clients when they connect and subscribe
to the Logging stream for the first time. Current default log history
length is 10,000 messages to support applications with chatty logging at
startup.
