feat: add TTLConfig

[mdonnalley]

Adds TTLConfig class for use by sf deploy metadata, sf env create scratch, sf env create sandbox

Example usage:

import { Global, TTLConfig } from '@salesforce/core';
import { Duration } from '@salesforce/kit';

type CachedOptions = {
  api: API;
  'target-org': Org | string;
  'test-level': TestLevel;
  'api-version'?: string;
  'dry-run'?: boolean;
  'ignore-errors'?: boolean;
  'ignore-warnings'?: boolean;
  manifest?: string;
  metadata?: string[];
  'source-dir'?: string[];
  tests?: string[];
  wait?: Duration;
  verbose?: boolean;
};

export class DeployCache extends TTLConfig<TTLConfig.Options, CachedOptions> {
  public static getFileName(): string {
    return 'deploy-cache.json';
  }

  public static getDefaultOptions(): TTLConfig.Options {
    return {
      isGlobal: false,
      isState: true,
      filename: DeployCache.getFileName(),
      stateFolder: Global.SF_STATE_FOLDER,
      ttl: Duration.days(1),
    };
  }
}

@mdonnalley Tests?

[peternhale]

@mdonnalley thanks for writing the tests!

empty cache would throw, but it'd be an index out of range?

[mshanemc]

I think I'd put a test case on the expected empty cache behavior
