72c16ad2c7 Close RPC connections after the web server is stopped.
Previously all of the shutdown tasks were running concurrently, which meant the RPC connections be closed before the webserver is finished using them.

4f2766352b Improve handling of fee status.
- Fee tx status is now tracked using a dedicated field, with values none/received/broadcast/confirmed/error.
- Fee tx hex and hash are now both set in /payfee. The absense of txhash is no longer used to determine if a fee tx has been broadcast or not.
- setvotechoices can no longer be called before a fee is received.
- Remove `binding:required` from response types. It has no effect on responses, it is only needed on request types which are validated by gin.

a6d9b79619 Tolerate dcrwallet connection failures.
If at least 1 wallet connection succeeds, vspd should proceed to use the connected wallet(s). Only error out if all wallet connections fail.

Calculate fee from percentage. (#69)
* Calculate fee from percentage.

- Reverted config to accept a fee percentage, not absolute value.
- The fee amount to be paid is now included in the `getfeeaddress` response. The current best block is used to calculate the fee percentage, and new blocks may be mined before the fee is paid, so the fee expiry period is shortened from 24 hours to 1 hour to mitigate this.
- Rename ticket db field to FeeAmount so it is more representative of the data it holds.
- API fields renamed to "FeePercentage" and "FeeAmount"
- Relay fee is still hard coded.

* Use getbestblockhash

Delay fee broadcast and adding tickets to wallets. (#62)
* Delay fee broadcast and adding tickets to wallets.

- Adds a `background` package which implements a dcrd notification handler.  On each blockconnected notification, tickets with 6+ confirmations are marked confirmed, relevant fee transactions are broadcast, and any fees with 6+ confirmations have their tickets added to voting wallets.
- VSP fee is now an absolute value measured in DCR rather than a percentage. This simplifies the code and is more appropriate for an MVP. We can re-add percentage based fees later.
- Database code for tickets is now simplified to just "Insert/Update", rather than having functions for updating particular fields.
- Pay fee response no longer includes the fee tx hash, because we dont necessarily broadcast the fee tx straight away.

* Const for required confs

Rework client/server authentication. (#58)
* Rework client/server authentication.

- Remove Signature from all requests, and instead expect a signature in HTTP header "VSP-Client-Signature".
- Remove CommitmentSignatures from the database.
- Use a bool flag to indicate when a ticket is missing from the database rather than an error.

This commit introduces a lot of duplication into each of the authenticated HTTP handlers. This should be removed in future work which moves the authentication to a dedicated middleware.

* Introduce auth and rpc middleware.

This removed the duplication added in the previous commit, and also removes the duplication of RPC client error handling.
