Remove legacy Mercury plugin and associated code

[samsondav]

To be merged after plugin has been replaced by LLO.

Blocked on:

1. Keystone (need to migrate DF2.0 to LLO and remove legacy scripts, etc)
2. Data Streams (need to fully sunset all legacy feeds)

Also to be updated after this is merged:

• chainlink-common (remove old legacy mercury loops plugin and related stuff)
• chainlink-data-streams (remove mercury directory)
