What this PR does / why we need it:
Bootstrap and Install Ansible roles applies kpt packages sequentially, resulting in long provisioning process. This change allows applying some kpt packages concurrently and delays the deployment waiting process after all the packages have been applied. This change shows a reduction in 20%

Task	Before	After
kpt	444.90s	258.70s
bootstrap	95.69s	115.89s
install	1.03s	21.51s

Which issue(s) this PR fixes:

NA

Special notes for your reviewer:

• Molecule version required to downgrade for accepting CPU/Memory definition.
• Fixed some linting issues not reported in the current version.
• Kpt packages seems to have some dependencies which results in partial concurrent implementation.
