Current organization is totally mess, there's actually no organization
at all for lots of commands.
Let's organize most commands based on CTRL node where they are applied:
global, bts, trx, etc.
Specific set of commands such as neighbor-related, rf-related, etc.
are left in separate files as subsections inside the same node, so the
hierarchy is still clear.
