Docs for SERVER-40462: Disallow transactions on shard servers with writeConcernMajorityJournalDefault = false

Description

Description:

This commits disallow multi-statement transactions on shard servers that have writeConcernMajorityJournalDefault = false.

Engineering Ticket Description:

Nodes running with the in-memory storage engine do not support transaction prepare and because of this, currently they cannot participate in cross-shard transactions.

On the chance that we start supporting that and in order to ensure that in-memory nodes and nodes running with writeConcernMajorityJournalDefault = false don't count towards the majority quorum for any w:majority writes done by the coordinator and participant, such writes should be done with j:true.

Scope of changes

• txn
• txn prod concern
• txn sharded clusters prod concern
• rs conf page
• For now, will not put in the limits/restriction page for sharded clusters operation.
