Subject: [PATCH] Closed loop use case driven yang models for O-DU

The following parameters were added according to the
RSAC 2021-04-08 meeting.

- administrative-state : type ENUM (read/write)
  allowedValues: LOCKED, SHUTTING_DOWN, UNLOCKED

- operational-state : type ENUM (read-only)
  allowedValues: ENABLED, DISABLED

- cell-state : type ENUM (read-only)
  allowedValues: IDLE, INACTIVE, ACTIVE

The RPCs are not needed anymore and therefore marked as deprecated.

The module has no errors and no warnings according to
pyang --lint.

IssueID: ODUHIGH-322
