"Configuration file not found in directory where diktat is run" warning is printed multiple times

[orchestr7]

For diktat running in console we print "Configuration file not found in directory where diktat is run" too many times, should be once. This issue can be duplicate.

Affects usability of a cli tool.

From the RuleSetProvider documentation (0.47.x):

This method is going to be called once for each file (which means if any of the rules have state or
are not thread-safe - a new RuleSet must be created).

This method is marked for removal in KtLint 0.48 for reason below:

For each invocation of KtLint.lint and KtLint.format the RuleSet is retrieved. This results in new
instances of each Rule for each file being processed. As of that a Rule does not need to be thread-safe.

However, KtLint.format requires the Rule to be executed twice on o a file in case at least one violation
has been autocorrected. As the same Rule instance is reused for the second execution of the Rule, the state
of the Rule is shared. As of this Rule have to clear their internal state.

So now rules are expected to have a state, and a new Rule instance is created per a file checked.
