Provide up to date drone compatibility environment variables to each step execution.
closes#1416
Before a step is executed, some environemnt variables are updated.
This ensures, that the updated environment variables are copied to their corresponding `DRONE_` environemt variables.
Side effect is that the `DRONE_` environemnt variables are no longer available in the metadata which should not harm as they are not used inside woodpecker.

Adds `ignore_failure` to pipeline steps. When it's set to true,
if the step fails the following steps continue to execute as if no failure had occurred.
---
failure enums idea:
* fail (default) = if other steps run in parallel, wait for them and
then let workflow fail
* cancel = if other steps run in parallel, kill them
* ignore = we mark the step as failed but it wont have any impact
When executing a backend step, in case of failure of the specific step, the run is marked as errored but the step error is missing.
Added:
1. Log for the backend error (without trace)
2. Mark the step as errored with exit code 126 (Could not execute).

Dropped support for `DRONE_*` environment variables in pipeline steps. Pipeline meta-data can be accessed with `CI_*` variables.
- `CI_*` prefix replaces `DRONE_*`
- `CI` value is now `woodpecker`
- `DRONE=true` has been removed
