I'm still reviewing these changes, but here are a few things I see.
I can run a test like:
1. Start server 1 with a gateway sender with
enforce-threads-connect-same-receiver=true
2. Start server 1 with a gateway sender with
enforce-threads-connect-same-receiver=false
The servers successfully start up in this case, but I don't think they
should with these conflicting property values.
The gfsh commands look like:
```
start server --name=server-A-1 --group=server-A-1
--locators=localhost[10331] --mcast-port=0 --server-port=0
start server --name=server-A-2 --group=server-A-2
--locators=localhost[10331] --mcast-port=0 --server-port=0
create gateway-sender --id=B --group=server-A-1
--remote-distributed-system-id=2 --enforce-threads-connect-same-receiver=true
create gateway-sender --id=B --group=server-A-2
--remote-distributed-system-id=2 --enforce-threads-connect-same-receiver=false
```
The generated xml looks like:
server-A-1:
```
<cache ...>
<gateway-sender enforce-threads-connect-same-receiver="true" id="B" .../>
</cache>
```
server-A-2:
```
<cache ...>
<gateway-sender enforce-threads-connect-same-receiver="false" id="B" .../>
</cache>
```
Here is an example where conflicting gateway sender parameters cause the
startup to fail:
```
create gateway-sender --id=B --group=server-A-1
--remote-distributed-system-id=2 --parallel=true
create gateway-sender --id=B --group=server-A-2
--remote-distributed-system-id=2 --parallel=false
```
This error message is logged:
```
Executing - create gateway-sender --id=B --group=server-A-2
--remote-distributed-system-id=2 --parallel=false

Something similar should happen with the
enforce-threads-connect-same-receiver property.
This check and error message are coming from
GatewaySenderAdvisor.checkCompatibility.
GatewaySenderProfile needs to be updated to include
enforceThreadsConnectSameReceiver. Here are some changes that do this:
```

With these changes, gfsh logs this error message:
```

--remote-distributed-system-id=2 --enforce-threads-connect-same-receiver=false

```
There might be a problem with these changes as written though. gfsh prevents
gateway senders from being created while all the members are not the current
version, but thats not true for GemFire xml.
If I run a test like this with these changes:
1. Start locator with an older version
2. Start several servers with GemFire xml
3. Bounce locator to a newer version
4. Start server with the newer version
In this case, I see an exception like this in the new server when it tries
to deserialize a GatewaySenderProfile from an older member:
```

```
I'm not sure if this case needs to be supported. If so, then the
GatewaySenderProfile toData/fromData will have to handle versioning.
btw - this same change might need to be made for the groupTransactionEvents
property.
