[ci] stop checking verification component
[ci] stop checking verification component

We are planning to redesign verification component and it will include a lot
of changes in code. To simplify review process, such changes should be
splitted as much as possible.

Current jobs will not work with new code, so we will need to rewrite them too.
To reduce workarounds(they will require a lot of additional lines of code), it
would be nice to temporary disable checking verificaiton component at all and
enable them again after redesign will be done.
