feat(chart): add custom args, hostPathMounts, and devices config

[aclerici38]

adds configuration for args,hostPath mounts, and devices to the chart.

Mounts can be configured under hostPathMounts in the values. The current default of /dev remains unless a mount under hostPathMounts mounts /dev (if someone wants to set readOnly for example) or begins with /dev/. For example if someone adds /dev/tun the default /dev will be removed.

When devices is set the default devices args are replaced.

Chart version also updated to 0.2.0.

Let me know if this is acceptable, thanks!!

Thank you @aclerici38! I need to run this locally to test that the generated manifests are actually produced with the right structure. It will probably make sense to add some kind of testing to the charts soon to validate that they generate correctly
