Combining `-add` and `-rm` flags on `docker service update` should
be usable to explicitly replace existing options. The current order
of processing did not allow this, causing the `-rm` flag to remove
properties that were specified in `-add`. This behavior was inconsistent
with (for example) `--host-add` and `--host-rm`.
This patch updates the behavior to first remove properties, then
add new properties.
Note that there's still some improvements to make, to make the removal
more granulas (e.g. to make `--label-rm label=some-value` only remove
the label if value matches `some-value`); these changes are left for
a follow-up.
Before this change:
-----------------------------
Create a service with two env-vars
```bash
docker service create --env FOO=bar --env BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Env }}' test | jq .
[
"FOO=bar",
"BAR=baz"
]
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --env-rm FOO --env-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Env }}' test | jq .
[
"BAR=baz"
]
```
Create a service with two labels
```bash
docker service create --label FOO=bar --label BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "bar"
}
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --label-rm FOO --label-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.Labels }}' test | jq .
{
"BAR": "baz"
}
```
Create a service with two container labels
```bash
docker service create --container-label FOO=bar --container-label BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "bar"
}
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --container-label-rm FOO --container-label-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
}
```
With this patch applied:

```
Update the service, and replace the value of `FOO` for a new value
```bash

{
"BAR": "baz",

}
```
Create a service with two container labels
```bash

docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "bar"
}
```
Update the service, and replace the value of `FOO` for a new value
```bash
docker service update --container-label-rm FOO --container-label-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "updated-foo"
