FE: KC: Removing KC cluster action is not disabled w/ r/o mode

[maver1ck]

Describe the bug (Actual behavior)
I enable read only mode for Kafka Cluster. Under this mode I'm able to remove Kafka Connect connector.

Expected behavior
I should't be able to remove Kafka Connect connector in read-only mode.

Set up

How do you run the app? Please provide as much info as possible:

1. App version: v0.5.0 (027d9b4)
2. Helm chart version, if you use one: kafka-ui-0.5.2
3. Any IAAC configs

yamlApplicationConfig:
  kafka:
    clusters:
      - name: bds
        bootstrapServers: "kafka:9092"
        schemaRegistry: "http://kafka-cp-schema-registry.default.svc:8081"
        readOnly: true
        kafkaConnect:
        - name: connect

As a quick workaround, you could use RBAC

@Haarolean
Is there a possibility to use RBAC without OAuth provider ?

[Haarolean]

@maver1ck not yet, unfortunately. We're planning on implementing LDAP/AD as well #2752. Is that a good method for you, what do you personally use?

[maver1ck]

I just wanted to give open read-only access to dev env :)
We don't have auth mechanism yet.

Hey @Haarolean
I did some initial investigation around the implementation of the features.
Came across following file,

Frontend -

/kafka-ui-react-app/src/components/Connect/List/ActionsCell.tsx

Backend -

/kafka-ui-api/src/main/java/com/provectus/kafka/ui/controller/KafkaConnectController.java

I'll be happy to contribute and fix the issue.

@sachin-duhan sure, please!
