.SYNOPSIS 
Retry to do the operation until it is executed successfully or has reached the maximum number of retry attempts. It returns the result of the operation if success. Otherwise, it returns null.
.PARAMETER operation
Specifies the operation which you want to retry. It is a script block. The format shoulde be {OPERATION}.
.PARAMETER description
Specifies the description of the operation.
.PARAMETER expectResult
Specifies the expect result. The default value is "$null" and it means not to check the result.
.PARAMETER maxRetryCount
Specifies the maximum retry count. The default value is 18.
.PARAMETER retryInterval
Specifies the retry interval. The default value is 10 seconds.
