Order Number is not sequence

[tonhuynh]

Our server host on Azure with 2 instances, and our order-number field hasn't been sequence.

• Order number template: CO{0:yyMMdd}-{1:D5}

Version info:

• Browser version:
• Platform version: 2.13.44
• Module version: 2.25.18

Expected behavior

OrderNumber must be sequence.

Actual behavior

Order number wasn't

Steps to reproduce

1. Commerce Manager: fixed 2 instances
2. Login to Storefront and create orders with multiple users, browsers as the same time.

Reason:

1. using InMemorySequenceList won't share memory between commerce instances.
2. When we turn Off Cookies on Storefront, this issue will happen.

Current implementation guarantees number uniqueness (in case of a date part presented in the template) and increasing sequence in case of one platform instance.
The strict increasing sequence with customization will be implemented at #146 (it is in progress now).
It will be done in v3 first.

Good to know that. Thanks @yecli
