fix: Create SRV domain_record

[yec-akamai]

📝 Description

Fix a bug that name is required together with type in the domain_record. For SRV domain record, service instead of name is used in domain record creation.

Addressed #521.

✔️ How to Test

make TEST_ARGS="-v domain_record" test

Manual test:

1. In a sandbox environment, run the following script to create a domain and a SRV domain_record under it.

- name: test
  hosts: localhost
  tasks:
    - name: Create domain
      linode.cloud.domain:
        domain: 'host.example.com'
        soa_email: 'realemail@example.com'
        type: 'master'
        state: present
      register: domain_create

    - name: Create an SRV domain record
      linode.cloud.domain_record:
        domain: '{{ domain_create.domain.domain }}'
        service: carddavs
        protocol: tcp
        type: 'SRV'
        target: host.example.com
        port: 443
        priority: 0
        weight: 1
        state: present

2. Observe that the domain_record is created successfully
