87ab3c806c feat(main): Parse timestamps out of journald entries
Instead of relying on Stackdriver's ingestion timestamps, parse
timestamps out of journal entries and provide those to Stackdriver.

If a timestamp could not be parsed out of a log entry, the ingestion
time is used as the fallback.

bd19132eff chore(main): Send logs in smaller chunks of 250 entries
In some cases sending 1000 entries seemingly results in a vague "Bad
request" error.

This reduces the chunk size to something that should be more
manageable.

54b03a8dad fix(main): Attempt to read with next_record before waiting
Without this fix new records are only "pushed out" when something
appends to the journal.

e4b4830a04 feat(main): Persist & load persisted cursor positions
Adds support for persisting the cursor position in a file (by default
`/var/journaldriver/cursor.pos`, overridable via the environment
variable `CURSOR_POSITION_FILE`).

This lets journaldriver resume from a known journal position after
service restarts.

This closes #3

10f23a9dfb feat(main): Implement parsing of JSON payloads
Stackdriver supports structured JSON payloads in addition to simple
plain-text payloads.

This commit introduces a new feature in which journaldriver will
attempt to parse incoming log messages into JSON vaues and forward
them as structured payloads if they are JSON objects.

Messages that can not be parsed into JSON objects will continue to be
forwarded as plain text messages.

4ef98fc2ba feat(main): Implement record conversion & flushing to API
This implements the "meat" of the initial version of journaldriver.

Records from journald are converted into the representation required
by Stackdriver and forwarded to the API.

In this initial version journaldriver is only supported on instances
running on GCP.

Stackdriver.
