Ed Welch 0352b75f0d Loki: Add new logql template functions `bytes`, `duration`, `unixEpochMillis`, `unixEpochNanos`, `toDateInZone`, `b64Enc`, and `b64Dec` (#8774) ... **What this PR does / why we need it**: This adds several new template functions to the logql to be used in `line_format` and `label_format` - bytes - duration (and duration_seconds) - unixEpochMillis - unixEpochNanos - toDateInZone - b64Enc and b64Dec `bytes` and `duration` adds parity with the `unwrap` pipeline stage in logql, allowing you to convert human readable versions of bytes and times into their respective primitives of bytes and seconds. This makes it possible to do math and comparisons of these extracted values in `line_format` and `label_format` `unixEpochMillis` and `unixEpochNanos` extends the existing `unixEpoch` function which can only generate seconds level precision to allow having millisecond and nanosecond level precision. `toDateInZone` allows for specifying a specific timezone when parsing a date. `b64Enc` and `b64Dec` allow base64 encoding and decoding values. **Which issue(s) this PR fixes**: Fixes #<issue number> **Special notes for your reviewer**: @JStickler I made a lot of changes to the template_functions.md doc page to try and create some more consistency as well as remove some notices that really aren't relevant anymore: * Tried to make sure every function had a `Signature` and `Examples` block * Removed a lot of `NOTE` about functions being introduced in a specific version * Removed documentation for some deprecated string functions (they still exist in code but I removed the docs for them, their exist better replacements for all of them) **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Documentation added - [x] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md` --------- Signed-off-by: Edward Welch <edward.welch@grafana.com>		3 years ago
