beaker 2.25.0

Bug

• [BKR-351] - output inside/below step should be indented properly
• [BKR-522] - Beaker should not use cached key pair on EC2
• [BKR-533] - Beaker's `confine` overwrites the array of all hosts
• [BKR-535] - Regression: confine_block does not skip tests with beaker 2.24.0
• [BKR-554] - Add AIX support for 'repo'/'package' installation

Improvement

• [BKR-532] - get beaker-hiera usage merged into beaker itself
• [BKR-545] - Solaris 11 should expect `p5p` for puppet-agent package files

New Feature

• [BKR-327] - Add support for EL7 to add_el_extras method

Task

• [BKR-564] - beaker no longer works on ruby 1.9.3
• [BKR-568] - no longer accept PRs marked as "(MAINT)"
