Add filter support for `network ls` to hide predefined network,
then user can use "docker network rm `docker network ls -f type=custom`"
to delete a bundle of userdefined networks.

## 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)
* name (network's name)
* type (custom|builtin)
#### 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.
#### 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 ps --filter name=foo
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
06e7eef0a170 foobar bridge
```
#### ID
The `id` filter matches on all or part of a network's ID.
The following filter matches all networks with a name containing the
`06e7eef01700` string.
```bash
$ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
NETWORK ID NAME DRIVER
63d1ff1f77b0 dev bridge
```

```bash

95e74588f40d foo bridge
