feat: add new options endpoint

[wa0x6e]

Closes https://github.com/snapshot-labs/workflow/issues/223

This PR adds a new options endpoint to return all data from the options table

Endpoint do not have any filter and pagination, and will always return all results.

Create the table with

CREATE TABLE options (
  name VARCHAR(100) NOT NULL,
  value VARCHAR(100) NOT NULL,
  PRIMARY KEY (name)
);

Then you can query with

query {
  options {
  	name 
  	value
	}
}

which should return something like

{
  "data": {
    "options": [
      {
        "name": "limit.test",
        "value": "12"
      }
    ]
  }
}

Insert data for mainnet (from https://github.com/snapshot-labs/snapshot-sequencer/blob/2a94d8fdcb592d9b087a33508eb02db76613cccd/src/helpers/limits.ts)

INSERT INTO `options` (`name`, `value`) VALUES
('ecosystem_spaces', 'orbapp.eth,cakevote.eth,outcome.eth,polls.lenster.xyz,daotest.dcl.eth,arbitrumfoundation.eth'),
('limit.active_proposals_per_author', '20'),
('limit.ecosystem_space.proposal.day', '150'),
('limit.ecosystem_space.proposal.month', '750'),
('limit.flagged_space.proposal.day', '0'),
('limit.flagged_space.proposal.month', '0'),
('limit.follows_per_user', '25'),
('limit.space.proposal.day', '3'),
('limit.space.proposal.month', '15'),
('limit.turbo_space.proposal.day', '40'),
('limit.turbo_space.proposal.month', '200'),
('limit.verified_space.proposal.day', '20'),
('limit.verified_space.proposal.month', '100');

Should be the same for testnet, beside ecosystem spaces, which should just be citiesdao.eth
