fix: use WriteOptions from ClientConfig on write

[jansimonb]

The issue

If the client is configured as:

InfluxDBClient client = InfluxDBClient.getInstance(
  new ClientConfig.Builder().host(host).token(token).database(database)
    .writePrecision(WritePrecision.S).build())

then the

client.writeRecord(r)

ignores the configured write precision and uses the default precision.

Proposed Changes

The following 4 write functions in InfluxDBClientImpl now are getting WriteOptions from ClientConfig config, (instead of the previously usedWriteOptions.DEFAULTS):

public void writeRecord(@Nullable final String record)
public void writeRecords(@Nonnull final List<String> records)
public void writePoint(@Nullable final Point point)
public void writePoints(@Nonnull final List<Point> points)
