As a CLI user I want to compile tabtests in the cloud

[knopki]

Rationale

There’s currently no way to run tabtest from xodc without gcc and make. Also, it's useful for the integration tests.

Usage

USAGE
  $ xodc tabtest [options] [entrypoint]

ARGUMENTS
  ENTRYPOINT
      Project and/or patch to operate on. The project should point to a file or
      directory on the file system. The patch may either point to file system or
      be a XOD patch path. If either is omitted, it is inferred from the current
      working directory or another argument. Examples:

         * ./path/to/proj.xodball main      # xodball + patch name
         * ./path/to/proj/main/patch.xodp   # just full path to a patch
         * main                             # a patch in the current project

OPTIONS
  -V, --version          show CLI version
  -h, --help             show CLI help
  -o, --output-dir=path  [default: /tmp/xod-tabtest] path to directory where to save tabtest data
  -q, --quiet            do not log messages other than errors
  -w, --workspace=path   [default: ~/xod] use the workspace specified, defaults to $HOME/xod
  --no-build             do not build
  --cloud                compile in the cloud
  --anonymous            when compile in the cloud do it anonymously
  --api=hostname         [default: xod.io] XOD API hostname
  --on-behalf=username   publish on behalf of the username
  --password=password    XOD API password
  --username=username    XOD API username

EXAMPLES
  Build tabtests for project in current working directory
  $ xodc tabtest

  Specify target directory and project, only generate tests
  $ xodc tabtest --no-build --output-dir=/tmp/xod-tabtest ./workspace/__lib__/xod/net

  Run tabtests for project in current working directory using XOD cloud
  $ xodc tabtest --cloud --anonymous

Acceptance criteria

• [ ] I can run all tabtests with exactly same bahaviour without installed dev tools
• [ ] xodc exits with non-zero code if a library can’t be installed
• [ ] Compilation limits exhausted error is handled gracefully
• [ ] Wrong credentials is nadled gracefully
• [ ] Network problem is handled gracefully
