SERVER-49336 Set ClientMetadata before CommandInvocations are run

This patch does the following:
- Always parses ClientMetadata before command implementations are run.
- Marks general ClientMetadata as final in the first hello.
- Removes client_metadata_ismaster.* (SERVER-50517)
- Switches references to "isMaster" to "hello" (SERVER-50517)
- Binds "$client" metadata as a decoration (SERVER-50804)
