Release 3.34.0 rc1

### 3.34.0

### Added Features:
- Make to_issuer, from_issuer optional on ripple payment
  Previously defaulted to COLD_WALLET

### Fixed Bugs:
- Bump bridge-quote-service-client version
- Remove logs/ directory from git
- Automatically create logs/ directory and log file
to prevent hoisting issues, move var declarations outside of conditional, and only assign var inside conditional:
```
var logDirectory, logFile;

if (!config.get('NODE_ENV').match('test')) {
  logDirectory = path.join(__dirname,'/../../logs');
...
```
