Inconsistency between README and code regarding sonar.gitlab.quality_gate_fail_mode

[p3k]

In the README it says (please note the case):

sonar.gitlab.quality_gate_fail_mode | Quality gate fail mode: error, warn or none (default error)

sonar-gitlab-plugin/README.md

Line 336 in ff206e1

| sonar.gitlab.quality_gate_fail_mode | Quality gate fail mode: error, warn or none (default error) | Administration, Variable | >= 3.0.0 |

…while in the Java code the properties are handled uppercase:

sonar-gitlab-plugin/src/main/java/com/talanlabs/sonar/plugins/gitlab/models/QualityGateFailMode.java

Line 24 in 5d3033c

ERROR("ERROR"), WARN("WARN"), NONE("NONE");

At least it becomes obvious that setting sonar.gitlab.quality_gate_fail_mode=none does not change anything while sonar.gitlab.quality_gate_fail_mode=NONE does.
