Added gm-token EA

[karen-stepanyan]

Closes DF-19319

Description

Added new gm-token composite EA to get a price of GM tokens. GM tokens (GM market pools) represent a market pool of a particular market for a specified asset pair.

A GM pool (GMX Market pool) consists of:

• Index Price Feed: Long and short tokens will be opened / closed based on this price feed
• Long Token: This is the token that will back long positions
• Short Token: This is the token that will back short positions

For example, a market could be ETH/USD[WETH-USDC], in this case:

• Index Price Feed: ETH/USD
• Long Token: WETH tokens back long positions
• Short Token: USDC tokens back short positions

The EA is made generic so that it can fetch the price of every possible GMToken.
In summary this is how gm-token EA works

1. Based on input request fetches bid/ask data for every asset from 3 source providers
2. Based on received data calculates the median bid/ask per asset
3. Fixes the prices to get rid of decimal points
4. Uses calculated median prices alongside with other config data to get the price of gmToken from GMX Reader contract

To test the EA, first run 3 source EAs that the gm-token is using for price data. Provide relevant env variables
TIINGO_ADAPTER_URL,
NCFX_ADAPTER_URL
COINMETRICS_ADAPTER_URL
Provide ARBITRUM_RPC_URL.

Run the gm-token EA. To get the gmToken price use one of following request data. The list of gmTokens and their prices can be found here.

Quality Assurance

• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant infra-k8s configuration file.
• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant adapter-secrets configuration file or update the soak testing blacklist.
• If a new adapter was made, or a new endpoint was added, update the test-payload.json file with relevant requests.
• The branch naming follows git flow (feature/x, chore/x, release/x, hotfix/x, fix/x) or is created from Jira.
• This is related to a maximum of one Jira story or GitHub issue.
• Types are safe (avoid TypeScript/TSLint features like any and disable, instead use more specific types).
• All code changes have 100% unit and integration test coverage. If testing is not applicable or too difficult to justify doing, the reasoning should be documented explicitly in the PR.
