[JENKINS-52041] can't use docker-compose - minimized workspace name start with underscore

For certain project names minimized workspace name will start with underscore:

// add this test case to WorkspaceLocatorImplTest

assertEquals("_my.service.name.abcde_PR-1-J66S6RX2LGBP3IYNJHSVLYWU5WQXTLZJDQRJIBNFPNM3HOWPZASQ",

  WorkspaceLocatorImpl.minimize("one/or/more/parent/elements/abcdefghijk/my.service.name.abcde/PR-1"));

docker-compose uses directory name as container name (-p can be used to set custom name).

Docker does not allow underscore as first letter of the container name.

Because of that jobs that call docker-compose without -p will fail.

Workarounds:

1) use docker-compose -p

2) use custom workspace name

3) jenkins.branch.WorkspaceLocatorImpl.PATH_MAX=0 (or other value)
