[idea] Ignore .idea/misc.xml which contains opened editor config

[easyCZ]

Description

When the IDE has panes open, it checks in cursor information into .idea/misc.xml with contents like

 <component name="UnattendedHostPersistenceState">
    <option name="openedFilesInfos">
      <list>
        <OpenedFileInfo>
          <option name="caretOffset" value="0" />
          <option name="fileUrl" value="file://$PROJECT_DIR$/components/content-service/pkg/initializer/prebuild.go" />
        </OpenedFileInfo>
      </list>
    </option>
  </component>

This information is only meaningful to the local opened instance of the IDE and shouldn't be checked in.

@akosyakov You've comitted the misc.xml into the repo originally, any particular reason that it should stay?

@easyCZ I don't really looked at content of idea folder, as far as I understand this folder already has .gitignore file which should remove files unrelated to project config.

The main motivation of having idea folder to be checked in to enable discovery of gradle modules. I'm fine to ignore more files if backend-plugin and its dependencies are still auto discovered on start.
