[126]Fix: Add wait time to allow for a folder or file to be created if it does not exist

[TinaMor]

PR Description

If a folder does not exist, wait for a predefined time (user-specified or default). In the logMonitor.json file, we will add a field for wait period, waitInSeconds, which will be the wait time in seconds. The value can range from 0-INFINITY.

• waitInSeconds = 0 When the value is zero(0), this is means that we do not wait and LogMonitor terminates with an error as is the current implementation.
• waitInSeconds = INFINITY In this case, LogMonitor will wait for the folder to be created.
• waitInSeconds = +integer When the value is a positive integer, LogMonitor will wait for a predefined time. Once the time elapses, LogMonitor will terminate with an error.

Edge cases:

• If the user does not specify the value of waitInSeconds, then a default value is used, waitInSeconds = 300, that is, 300seconds (5 minutes).
• If a user provides an invalid value, a value less than 0, a warning message is shown and the default value is used.
