improvements: Add ability to specify multiple denoms in values.yaml

## Overview
Currently we are using `coins: 100000000000000uosmo,100000000000000uion` and `denom` in the default `values.yaml` file in `defaultChains`.

The side effect of this is, the registry service is currently only able to show a single denom in the assetlist.

## Proposal
Ability to specify multiple denoms as per the chain in the default values (based on the actual chain-registry)
```yaml
defaultChains:
osmosis:
image: anmol1696/osmosis:latest
home: /root/.osmosisd
binary: osmosisd
prefix: osmo
denom: uosmo
denoms:
- name: osmo
# ", "
units: "uosmo, osmo"
- name: ion
units: "uion, ion"
coins: 100000000000000uosmo,100000000000000uion
hdPath: m/44'/118'/0'/0/0
coinType: 118
repo: https://github.com/osmosis-labs/osmosis
```

Add tests in the e2e package to make sure this runs always
