add network dict with ipv6

[mcevik0]

network dictionary added to the docker-compose.yml with IPv6 subnet enabled.
services are attached to the (docker) network.
This addition will make the containers be connected to an IPv6 subnet, so that on IPv6-only hosts (eg. FABRIC sites STAR, HAWI) can be used to run the tests.

This change should be tested on both IPv6-only and IPv4 hosts. I did not have time to complete the tests yet.

[mcevik0]

@italovalcy @gretelliz
I reflected the changes from 05d89b6 to this branch (docker-compose.yml file) and tested on FABRIC VMs (should be no different on any other VMs regardless)
You may consider reviewing and merging these changes for IPv6-only setups.

--
Use FABRIC slices with https://github.com/atlanticwave-sdx/sdx-deployment/tree/main/awsdx-jupyter/fabric/sdx-end-to-end-tests

IPv6 site (TACC) worked well for completion of the tests.
awsdx-e2e-ipv6-tacc.pdf

IPv4 site (FIU) worked well for completion of the tests.
awsdx-e2e-ipv4-fiu.pdf

Although tests are completed on both of the VMs, they showed different results.

Hi Mert, thanks for submitting the PR for adding support for IPv6. Just for us to understand: is there anything that is being impacted by the lack of IPv6 support at this point?

The reason I'm asking this, and also the reason why we didnt apply this PR at this point, is that the integration with OESS and Juniper vMX presented some challenges for this new ipv6 setup that I'm still trying to figure it out. Understanding how critical IPv6 support is would help us prioritize this.

[mcevik0]

No, there is nothing being impacted by the lack of IPv6 support.
Only you cannot use a server that has only IPv6 address to connected to public internet for these tests. Probably this is not a limitation for the primary needs. So, this PR can be closed. Please let me know If you want me to close it and discard the branch, or you can close it immediately as well.

Hi Mert! thank you for clarifying this point! My suggestion them is that we keep this PR open for now while we figure this integration with OESS Juniper vMX first. I will try to handle this until the end of the week and I will let you know, okay?

[mcevik0]

Sure. And I really don't have any kind of dependency to these changes.
There has been some conversations about where to use for executing the end to end tests in the last few days/weeks, and I suggested any of the research testbeds could be used (Cloudlab, Chameleon, FABRIC etc), then specifically while verifying FABRIC, these changes became necessary only for the sites that are IPv6-only (the ones that their management network to connect VMs to public access are via IPv6 subnets). Otherwise, there is no such immediate need, so it can wait or it can be discarded.
