Refactor release yaml to use Build and push Docker image (teragrep#65)

* DockerFile

* Fixes for pull request 63

* removed unnecessary war file

* Added docker directory to RAT exclude because coverity fails and they don't require licensing

* Removed Coverty from CI

* Swapped Dockerfile location and swapped war location to use war file that release pipeline creates

* Dockerfile added to excluded rat list

* CFE-18 was with lowercase and not dash

* Return Coverity for merging to main repository

* Documentation changes for usage instructions

* Disable coverity for github actions testing

* Write-all was suggested in github issues. Testing that

* Wrong line. Trying again

* Build and push image test 1

* Removed external metadata gathering and using variables for tagging

* Doesn't recognize repo_lc so removing that to test if it works without

* Removed docker buildx

* Removed docker buildx

* Accidental dash in yaml :)

* Revert "Disable coverity for github actions testing"

This reverts commit de00fe2.
