Moving files/folders inside a storage or to another storage via GUI

### Background
Currently, via GUI users can't move files or folders in storage to any other place of the storage "hierarchy". It would be convenient to have the ability to move files or folders - to another folder of the storage or to another storage.

When user selects some files/folders in the storage, the **Move** button shall appear. If user clicks it - the modal window appears, in which user can choose where to move selected files/folders.
- GUI of the modal window and its behavior might be similar as selecting **Destination** folder for the "Transferring to the Cloud" feature via `Metadata` object
- user shall have an ability to move objects inside the single storage (selecting specific folder in the storage inner "hierarchy"), or to another one
- user shall have an ability to move objects between storages of one Cloud Region and between storages that belong to the different Regions
- this feature shall be available for both - `Object Storages` and `FS mounts`
