Make organizations websocket client to use JSON RPC

[mshaposhnik]

Description

Since we're removing support of the everrest websockets (#5357), all clients should use json rpc now.
The new protocol for organization events and membership events is following:

• Organization events (renamed, removed):

Subscription request:

{  
    "jsonrpc":"2.0",
    "method":"subscribe",
    "params":{  
        "method":"organization/statusChanged",
        "scope":{  
            "organizationId":"organizationl5oqb2ybtkjwdo64"
        }
    }
}

Event notification (organization removed):

{  
    "jsonrpc":"2.0",
    "method":"organization/statusChanged",
    "params":{  
        "members":[  
            "b07e3a58-ed50-4a6e-be17-fcf49ff8b242"
        ],
        "type":"ORGANIZATION_REMOVED",
        "organization":{  
            "qualifiedName":"awetwertwerqwerwe",
            "name":"awetwertwerqwerwe",
            "id":"organizationryrfleadd2so7d45",
            "links":[]
        },
        "initiator":"admin"
    }
}

Event notification (organization renamed):

{  
    "jsonrpc":"2.0",
    "method":"organization/statusChanged",
    "params":{  
        "newName":"awetwertwerqwerwe",
        "oldName":"awetwert",
        "type":"ORGANIZATION_RENAMED",
        "organization":{  
            "qualifiedName":"awetwertwerqwerwe",
            "name":"awetwertwerqwerwe",
            "id":"organizationryrfleadd2so7d45",
            "links":[]
        },
        "initiator":"admin"
    }
}

• Membership events (member added, member removed):

Subscription request:

{  
    "jsonrpc":"2.0",
    "method":"subscribe",
    "params":{  
        "method":"organization/membershipChanged",
        "scope":{  
            "userId":"d802c8b9-5b81-4a23-9d60-a1b056bc7050"
        }
    }
}

Event notification (member added):

{  
    "jsonrpc":"2.0",
    "method":"organization/membershipChanged",
    "params":{  
        "member":{  
            "aliases":[],
            "links":[],
            "name":"uy7c",
            "email":"test1@yahoo.com",
            "id":"d802c8b9-5b81-4a23-9d60-a1b056bc7050"
        },
        "type":"MEMBER_ADDED",
        "organization":{  
            "qualifiedName":"weweffwf",
            "name":"weweffwf",
            "id":"organizationf23fpsyo5b17k38j",
            "links":[]
        },
        "initiator":"admin"
    }
}

Event notification (member removed):

{  
    "jsonrpc":"2.0",
    "method":"organization/membershipChanged",
    "params":{  
        "member":{  
            "aliases":[],
            "links":[],
            "name":"uy7c",
            "email":"test1@yahoo.com",
            "id":"d802c8b9-5b81-4a23-9d60-a1b056bc7050"
        },
        "type":"MEMBER_REMOVED",
        "organization":{  
            "qualifiedName":"weweffwf",
            "name":"weweffwf",
            "id":"organizationf23fpsyo5b17k38j",
