Kai Qiang Wu(Kennan) f812b55692 Add network label filter support
This patch did following:

1) Make filter check logic same as `docker ps ` filters

Right now docker container logic work as following:
when same filter used like below:
 -f name=jack -f name=tom
it would get all containers name is jack or tom(it is or logic)

when different filter used like below:

 -f name=jack -f id=7d1
it would get all containers name is jack and id contains 7d1(it is and logic)

It would make sense in many user cases, but it did lack of compliate filter cases,
like "I want to get containers name is jack or id=7d1", it could work around use
(get id=7d1 containers' name and get name=jack containers, and then construct the
final containers, they could be done in user side use shell or rest API)

2) Fix one network filter bug which could include duplicate result
when use -f name=  -f id=, it would get duplicate results

3) Make id filter same as container id filter, which means match any string.
not use prefix match.

It is for consistent match logic

Closes: #21417

# NAME
docker-network-ls - list networks
# SYNOPSIS
**docker network ls**
[**-f**|**--filter**[=*[]*]]
[**--no-trunc**[=*true*|*false*]]
[**-q**|**--quiet**[=*true*|*false*]]
[**--help**]
# DESCRIPTION
Lists all the networks the Engine `daemon` knows about. This includes the
networks that span across multiple hosts in a cluster, for example:
```bash
$ docker network ls
NETWORK ID NAME DRIVER
7fca4eb8c647 bridge bridge
9f904ee27bf5 none null
cf03ee007fb4 host host
78b03ee04fc4 multi-host overlay
```
Use the `--no-trunc` option to display the full network id:
```bash
$ docker network ls --no-trunc
NETWORK ID NAME DRIVER
18a2866682b85619a026c81b98a5e375bd33e1b0936a26cc497c283d27bae9b3 none null
c288470c46f6c8949c5f7e5099b5b7947b07eabe8d9a27d79a9cbf111adcbf47 host host
7b369448dccbf865d397c8d2be0cda7cf7edc6b0945f77d2529912ae917a0185 bridge bridge
95e74588f40db048e86320c6526440c504650a1ff3e9f7d60a497c4d2163e5bd foo bridge
63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161 dev bridge
```
## Filtering
The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
Multiple filter flags are combined as an `OR` filter. For example,
`-f type=custom -f type=builtin` returns both `custom` and `builtin` networks.
The currently supported filters are:
* id (network's id)
* label (`label=<key>` or `label=<key>=<value>`)
* name (network's name)
* type (custom|builtin)
#### ID
The `id` filter matches on all or part of a network's ID.
The following filter matches all networks with an ID containing the
`63d1ff1f77b0...` string.
```bash
$ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
NETWORK ID NAME DRIVER
63d1ff1f77b0 dev bridge
```
You can also filter for a substring in an ID as this shows:
```bash
$ docker network ls --filter id=95e74588f40d
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
$ docker network ls --filter id=95e
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
```
#### Label
The `label` filter matches containers based on the presence of a `label` alone or a `label` and a
value.
The following filter matches networks with the `usage` label regardless of its value.
```bash
$ docker network ls -f "label=usage"
NETWORK ID NAME DRIVER
db9db329f835 test1 bridge
f6e212da9dfd test2 bridge
```
The following filter matches containers with the `usage` label with the `prod` value.
```bash
$ docker network ls -f "label=usage=prod"
NETWORK ID NAME DRIVER
f6e212da9dfd test2 bridge
```
#### Name
The `name` filter matches on all or part of a network's name.
The following filter matches all networks with a name containing the `foobar` string.
```bash
$ docker network ls --filter name=foobar
NETWORK ID NAME DRIVER
06e7eef0a170 foobar bridge
```
You can also filter for a substring in a name as this shows:
```bash
$ docker network ls --filter name=foo
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
06e7eef0a170 foobar bridge
```
#### Type
The `type` filter supports two values; `builtin` displays predefined networks
(`bridge`, `none`, `host`), whereas `custom` displays user defined networks.
The following filter matches all user defined networks:
```bash
$ docker network ls --filter type=custom
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
63d1ff1f77b0 dev bridge
```
By having this flag it allows for batch cleanup. For example, use this filter
to delete all user defined networks:
```bash
$ docker network rm `docker network ls --filter type=custom -q`
```
A warning will be issued when trying to remove a network that has containers
attached.
