Execute additional BLs with decreased LoE on already-awarded agreement (contract mod process)

[jonnalley]

User Story

As an OPRE COR, I want to alter budget line(s) on an awarded contract in order to reflect a decreased LoE contract modification.

Preconditions

• A contract exists with one or more BLs in Obligated status and with one or more BLs in Planned status

Acceptance Criteria

• User can remove a budget line already in Planned status. <---we've never done removing/deleting BLs yet... :eyes? Is that allowed? zero out?
• User can remove an entire services component? <--what happens to existing BLs on the SC?
• The user could also decrease an existing Planned BL's amount in addition to or instead of removing a SC/BL mentioned in the previous AC while also requesting the status change of that BL to executing.
• User can choose to move an existing Planned BL from one existing Services Component to another existing Services Component.
• The above actions should be limited to current and existing restrictions on users possessing roles that can alter or request a BL status change.
• Unlike a new contract entering the procurement process originally, the procurement tracker for these scenarios should be different.
• All relevant event / history records should be recorded denoting the who (user), when, and what, and remote IP of changes being made/requested.
