Fix issue #6

[Assaro]

• Fixed issue #6
• Error occured due to large dockers not being able to stop before the check occurred
• Instead of a single check after 5 seconds, there will be multiple checks to see if a DockerCommand has succeeded
• Added two new settings, Retries and TimeBeforeRetry to specify the checks
• Retries specifies the amount of checks before a DockerCommand action is considered to have failed
• TimeBeforeRetry defines the Time between two checks, in seconds
• The Time for those checks will be calculated and shown in the discord message until they have been completed
