feat: added multiple options to http commands (#8571)

# Description

All `http` commands now have a `-f` flag which for now contains the
`headers`, `body` and `status` fields (we can later add stuff like
`is-redirect` or `cookies`).

*Try it yourself*
```
http get http://mockbin.org/bin/630069dc-2c09-483a-a484-672561b7de14
http get -f http://mockbin.org/bin/630069dc-2c09-483a-a484-672561b7de14
```

The `http` commands can also now use the `-e` flag, which stands for
`--allow-errors`. When the status code is `>= 400`, it will still allow
you to interpret it like a normal response.

*Try it yourself*
```
http get http://mockbin.org/bin/2ebd3d27-bdc2-4ee8-b042-0bc2c0d1ad2a # should fail like usual
http get -e http://mockbin.org/bin/2ebd3d27-bdc2-4ee8-b042-0bc2c0d1ad2a # will return the body
http get -e -f http://mockbin.org/bin/2ebd3d27-bdc2-4ee8-b042-0bc2c0d1ad2a # will let you see the full response
```

# User-Facing Changes

- Adds `-f` (`--full`) to all `http` commands
- Adds `-e` (--allow-errors) to all `http` commands
