Adding a healthcheck command to an ECS container definition
results in an invalid command after synthesizing.

Before:

Input: ['CMD', 'command']
Output:
      HealthCheck:
        Command:
          - CMD
          - CMD
          - echo
          - z

Input: ['CMD-SHELL', 'command']
Output:
      HealthCheck:
        Command:
          - CMD
          - CMD-SHELL
          - echo
          - z

After:

Input: ['CMD', 'command']
Output:
      HealthCheck:
        Command:
          - CMD
          - echo
          - z

Input: ['CMD-SHELL', 'command']
Output:
      HealthCheck:
        Command:
          - CMD-SHELL
          - echo
          - z

fixes #2461

Can you add a unit test to ensure that this check is working as expected?

@pkandasamy91 the existing test should be sufficient.
