Observa uma variável específica e aguarda uma alteração no valor dela. Quando há uma alteração, este método retorna o novo valor ou esgota o tempo limite.
Se uma variável for excluída durante a observação, o estado variableState será definido como DELETED, e o método vai retornar a última variável conhecida value.
Se você definir o prazo de observação para um valor maior que o tempo limite interno (60 segundos), o valor atual da variável será retornado e o variableState será VARIABLE_STATE_UNSPECIFIED.
Se especificado, verifica o carimbo de data/hora atual da variável. Se o carimbo de data/hora atual for mais recente do que o newerThan, o método será retornado imediatamente.
Se não for especificado ou se a variável tiver um timestamp mais antigo, o inspetor aguardará uma alteração no valor antes de ser retornado.
Um carimbo de data/hora no formato UTC “Zulu” RFC3339, medido com precisão de nanossegundos. Exemplo: "2014-10-02T15:01:23.045123456Z".
