The regex used to describe the max-file and max-size logging options for
the json-file logger were incorrect. The regexes would only match a
single character (a digit or a literal +). Instead the regexes should
match 1 or more digits.
The character class for the units of the max-size also included a pipe
which meant that the regex would match 1| instead of only matching 1m,
1k, and 1g.

New driver options:
- `splunk-gzip` - gzip compress all requests to Splunk HEC
(enabled by default)
- `splunk-gzip-level` - change compression level.
Messages are sent in batches by 1000, with frequency of 5 seconds.
Maximum buffer is 10,000 events. If HEC will not be available, Splunk
Logging Driver will keep retrying while it can hold messages in buffer.
Added unit tests for driver.

`--log-opt splunk-format=inline|json|raw` allows to change how logging
driver sends data to Splunk, where
`inline` - default value, format used before, message is injected as a
line in JSON payload
`json` - driver will try to parse each line as a JSON object and embed it
inside of the JSON payload
`raw` - driver will send Raw payload instead of JSON, tag and attributes
will be prefixed before the message
`--log-opt splunk-verify-connection=true|false` - allows to skip
verification for Splunk Url

that were there intentially to force a line-break
also removes a duplicate redirect, that was present

Looks like there's issues with sourceforge project
pages. Given that sourceforge isn't really what
it used to be, trying to find alternative URLs

Previously, 'local.target' was used which is not going to work
out-of-the-box for lots of users.
The 'default.target' is the default unit systemd starts at bootup and
hence what most users would be expected to use.

This flags enables full support of daemonless containers in docker. It
ensures that docker does not stop containers on shutdown or restore and
properly reconnects to the container when restarted.
This is not the default because of backwards compat but should be the
desired outcome for people running containers in prod.

This does a minor cleanup of the logging driver
documentation;
- Add a table-header to the driver-options
table.
- Add language hints to code-blocks to
prevent incorrect highlighting
- Wrap some code examples so that they
fit in the default layout
- Wrap text to 80-chars
- Fix ordering in menu
- Some minor rewording
We should still create separate pages
for all available drivers (for example,
json-file, syslog, and GELF don't have
their own configuration page)

This fix tries to address the issue raised in #22358 where syslog's
message tag always starts with `docker/` and can not be removed
by changing the log tag templates.
The issue is that syslog driver hardcodes `path.Base(os.Args[0])`
as the prefix, which is the binary file name of the daemon (`dockerd`).
This could be an issue for certain situations (e.g., #22358) where
user may prefer not to have a dedicated prefix in syslog messages.
There is no way to override this behavior in the current verison of
the docker.
This fix tries to address this issue without making changes in the
default behavior of the syslog driver. An additional
`{{.DaemonName}}` has been introduced in the syslog tag. This is
assigned as the `docker` when daemon starts. The default log tag
template has also been changed from
`path.Base(os.Args[0]) + "/{{.ID}}"` to `{{.DaemonName}}/{{.ID}}`.
Therefore, there is no behavior changes when log-tag is not provided.
In order to be consistent, the default log tag for fluentd has been
changed from `docker.{{.ID}}` to `{{DaemonName}}.{{.ID}}` as well.
The documentation for log-tag has been updated to reflect this change.
Additional test cases have been added to cover changes in this fix.
This fix fixes#22358.

Since 1.9, driver specific log tag options
`syslog-tag`
`gelf-tag`
`fluentd-tag`
have been deprecated in favor of the generic tag
option which is standard across different logging
drivers.
This fix removed the deprecated driver specific
log tag options of `syslog-tag`, `gelf-tag`,
`fluentd-tag` for 1.12 and updated the docs.

the documentations says that you can drop "a file" into the
`docker.service.d` directory, but does not note that the file must end
with `.conf` in order to be recognized by systemd. This can lead to
some [confusion][] if readers are not previously familiar with
systemd.

This fix tries to add an additional syslog-format of `rfc5424micro` which follows
the same as rfc5424 except that it use microsecond resolution for timestamp. The
purpose is to solve the issue raised in #21793 where log events might lose its
ordering if happens on the same second.
The timestamp field in rfc5424 is derived from rfc3339, though the maximium
resolution is limited to "TIME-SECFRAC" which is 6 (microsecond resolution).
The appropriate documentation (`docs/admin/logging/overview.md`) has been updated
to reflect the change in this fix.
This fix adds a unit test to cover the newly introduced format.
This fix fixes#21793.
