Documentation for nested transactions/ savepoints

[chaserelock]

I believe this holds true for v4 and v5.
The transaction options object can take the key transaction which will be set to this.parent
https://github.com/sequelize/sequelize/blob/v4/lib/transaction.js

That is not reflected in the documentation for transaction, nor any SAVEPOINTing behavior:
http://docs.sequelizejs.com/class/lib/sequelize.js~Sequelize.html#instance-method-transaction

PR is welcome, there's some minor docs in the TS section of sequelize.

Googling about how to use savepoints led me to this undocumented feature. From here: https://stackoverflow.com/questions/38069797/easy-way-to-handle-nested-transactions

Longer form docs would certainly be great, but the JSDoc for sequelize.transaction should also be updated to include the transaction option: https://github.com/sequelize/sequelize/blob/e1446837196c07b8ff0c23359b958d68af40fd6d/src/sequelize.js#L1076-L1085

Also needed in transaction.js: https://github.com/sequelize/sequelize/blob/e1446837196c07b8ff0c23359b958d68af40fd6d/src/transaction.js#L13-L19
