feat(max-attempts): support retry limits

[emelski]

Allow users to optionally specify a maximum number of attempts to send in case of retryable errors, instead of retrying indefinitely.

• The logger will accept an integer "maxAttempts" option, which gives the total number of attempts (including the first) when retryable errors are encountered.

• When the limit is reached, errors that would otherwise be considered retryable are instead treated as non-retryable.

• If "maxAttempts" is negative (or not specified), the logger will continue to retry indefinitely.

• lib/logger.js: Add definitions and initialization for maxAttempts. Add convenience method _shouldRetry() to determine whether or not to retry given a specific error code.

• lib/constants.js: Add MAX_ATTEMPTS default value.

• test/logger-errors.js: Add a test to verify that retries are limited.

• test/logger-instantiation.js: Add a test for maxAttempts option validation.

• test/common/create-options.js: Update test support code.
