Expand integration documentation about docs HOT 2 OPEN

Have started on a few of these:

• How to add a token onto the Assets page
• How to register onto Assetlists
• How to register onto Cosmos Chain Registry
• How to transfer CW20 tokens between zones

intent to work on a few more very soon:

• How to add a pool onto the Trade page
• How to add External Incentive Gauges onto Pools page

as well, being a member of the OMM, I'd like to work on marketing-relayed pages:

• How to sponsor a Twitter Contest
• Request Social Media promotion

I also don't have any issue discussing with other projects for a new ones like:

• How to add Assets to info.osmosis.zone (I can discuss with Imperator on this)
• How to add Assets to Comsos Tokens page (Sunny used to work for Tendermint, so he might know)
• How to integrate onto Mintscan (no idea whom to talk to so far)

also, I think we are in dire need of assistance for relaying, hence I propose:

• Shop for Relayer as a Service (RaaS) Providers
  and
• Request support for setting up a Relayer
  To go along with: How to validate IBC token transfers

finally, thought it might be nice to have one:

• How to enlist onto Map of Zones

This is amazing 🔥 🔥 🔥
We will setup a call next week to go over the best layout and location on the UI for these docs and the other you are working on.
