Proposed changes

          ipv4:
            # Set the default for whether Bidirectional Forwarding Detection is enabled for PIM.
            bfd: <bool>
            bidirectional: <bool>
            hello:
              # Number of missed hellos after which the neighbor expires. Range <1.5-65535>.
              count: <str>
              # PIM hello interval in seconds.
              interval: <int; 1-65535>

How to test

Use case example

ethernet_interfaces:
  - name: Ethernet1
    pim:
      ipv4:
        bfd: true
        bidirectional: true
        hello:
           count: 2.5
           interval: 1

should render:

interface Ethernet1
   pim ipv4 bidirectional
   pim ipv4 hello interval 1
   pim ipv4 hello count 2.5
   pim ipv4 bfd
