ResetAsync() 공개 메소드

Creates a task that is completed when lock is in Unset state and no reset waiters are in front of current one and all tokens that were issued prior this one are released
Method tries to replace current tail with the new Reset TokenSource (when its task is completed, lock will be in Unset state), and if it fails, it means that another thread has updated the tail, so method tries again with that new tail. If there is no tail, it is considered that lock is in the Unset state already, but no one has requested a token yet If there is a tail, method tries to set its TokenSource.Next to the new TokenSource, and if it fails, it means that another thread has updated the property or the tail, so method tries again with that new tail. If replacing tail succeeded, method stops adding Set tokens. If there are no unreleased set tokens, new tail task is set to completed.
