Missing dependency in PyPi package

[geimer]

Describe the bug
The CodeChecker PyPi package seems to be missing a dependency on thrift. While subcommands like log or analyze work as expected, running CodeChecker without any arguments throws annoying exceptions before printing usage information. I haven't tried running any of the web commands (where thrift seems to be used), but I expect some issues there as well.
