[15.0][ENH] base_tier_validation, add Notify Reviewers by Approve Sequence

[kittiu]

This enhancement add another option for Tier Definition.

Notify reviewer by sequence

Use with 'Approve by sequence' to ensure that, the next reviewer will be notified only when he/she is the next approver in sequence.

Note:

• This works independently from 'Notify reviewers on creation', so it shouldn't be used together.
• This method will not add subscription and will not notify any other followers except the reviewer.

On first sight, this looks like an alternative implementation of https://github.com/OCA/server-ux/pull/638 base_tier_validation_waiting?

The use case you describe is available in V17. So maybe backport?

@bosd Hi, Thank you for suggest.

I tested on v17. it working :+1: but i test on your pr https://github.com/OCA/server-ux/pull/638 but still send email duplicate.

I think I can't backport from v17 to v15 because structure code base_tier_validation has changed.

However, this PR shouldn't merged to v15
