Add automatic retry options for certain functions

[Gintaras]

In next LA added wait.retry. It executes your code and waits/retries while it throws an exception.
 

Code:

Copy      Help

string file = @"C:\Test\test.txt";
string s = wait.retry(5, () => File.ReadAllText(file));
s = s.Upper();
wait.retry(5, () => { File.WriteAllText(file, s); });
print.it("ok");

Code:

Copy      Help

wait.retry(new(5) { Period = 100 }, () => { File.WriteAllText(file, s); });

wait.retry(5, () => { File.WriteAllText(file, s); }, e => e is IOException);
