[*] Added import from libdapConnector module correctly. Now no need for every call from libdapConnector no need to add module name

The function dap_dane has been changed, the closing of the configuration file has been added. Changed the test, removed the extra line break.

I brought the file with the main_test test in order. Now main_test.py returns the final code, creates a configuration file as in libdap, so that the test passes, replaces all print with logIt.

Corrected. Now the log_it function accepts not JSON as input, but two parameters — the level of logging and the displayed string.
Corrected. The setLogLevel function does not accept a string with a level name, but a parameter from the LogLevel enumeration.
Accordingly, the LogLevel enumeration has been added, which contains logging levels from debug to critical.

Redid the libdapConnector. Now it is not built on class, but on functions, as was indicated in the problem.

Changed initialization and log_it function. Now functions accept not one line with the separation of the characters '\n', but several parameters separated by commas.

Added functions configGetItem and configGetItemDefault. They accept a section, a key, and the second function accepts a default value. These functions take parameters as strings and return string. Also added a test for these functions.

The wrapping of the log_it function has been added, a test has also been added for the fact that it works
