  This init container will import custom .pem certificates to truststoreONAPall.jks
  Custom certificates must be placed in common/certInitializer/resources directory.

  The feature is enabled by setting Values.global.importCustomCertsEnabled = true
  It can be used independently of aafEnabled, however it requires the same includes
  as describe above for _initContainer.

  When AAF is enabled the truststoreONAPAll.jks (which contains AAF CA) will be used
  to import custom certificates, otherwise the default java keystore will be used.

  The updated truststore file will be placed in /updatedTruststore and can be mounted per component
  to a specific path by defining Values.certInitializer.truststoreMountpath (see _trustStoreVolumeMount)
  The truststore file will be available to mount even if no custom certificates were imported.
