feat(functional): make the functional api client a pure function.

[hrsh7th]

Summary

Currently, the functional api client does not support tree-shaking.
This PR solves the problem.

Fixes #97

Test Plan

I'll update the snapshot testing.

Example output

...

export const RolloutService_SetRolloutImage = <RequestOption>(apiClient: ApiClient<RequestOption>, params: Params$RolloutService_SetRolloutImage, option?: RequestOption): Promise<Response$RolloutService_SetRolloutImage$Status$200["application/json"]> => {
    const url = `/api/v1/rollouts/`;
    const headers = {
        "Content-Type": "application/json",
        Accept: "application/json"
    };
    return apiClient.request("PUT", url, headers, params.requestBody, undefined, option);
};
export const RolloutService_UndoRollout = <RequestOption>(apiClient: ApiClient<RequestOption>, params: Params$RolloutService_UndoRollout, option?: RequestOption): Promise<Response$RolloutService_UndoRollout$Status$200["application/json"]> => {
    const url = `/api/v1/rollouts/`;
    const headers = {
        "Content-Type": "application/json",
        Accept: "application/json"
    };
    return apiClient.request("PUT", url, headers, params.requestBody, undefined, option);
};
export const RolloutService_Version = <RequestOption>(apiClient: ApiClient<RequestOption>, option?: RequestOption): Promise<Response$RolloutService_Version$Status$200["application/json"]> => {
    const url = `/api/v1/version`;
    const headers = {
        Accept: "application/json"
    };
    return apiClient.request("GET", url, headers, undefined, undefined, option);
};

...

I don't know why but the url variable is corrupted now...

I can't understand the reason but this code isn't worked.

The class part works fine but function part will be wrong template string.

[hrsh7th]

each functions are now accept the apiClient argument and RequestOption type argument.

[hrsh7th]

the apiClient argument was added here.

[hrsh7th]

the functional api client will be list of ArrowFunctions now.
