Support BuildConfig.spec.source.contextDir starting with '/'

[basilv]

When trying to reuse a provided OpenShift buildConfig template, they sometimes include a source.contextDir setting. In some cases (e.g. BCgov backupcontainer), the project's Dockerfile is expecting a contextDir to be used in the BuildConfig.

Context directories starting with a slash (e.g. '/docker') cause nrdk build to fail, it appears this happens in nrdk/src/pipeline-cli/openshift-client-x.ts when calling git rev-parse HEAD:${contextDir} (

nrdk/src/pipeline-cli/openshift-client-x.ts

Line 291 in 1b49455

.execSync('git', ['rev-parse', `HEAD:${contextDir}`], {

). The simple fix appears to be to strip the leading slash off of contextDir before invoking git rev-parse.

The workaround is to remove the leading slash from the contextDir value in the buildConfig template.
