Merge PRs from PyDrive

[efiop]

E.g. iterative/dvc#3161 (comment)

[shcheklein]

can we close this?

[efiop]

@shcheklein We didn't merge all of them yet.

[shcheklein]

@efiop is there a list of PRs we want to merge?

[efiop]

@shcheklein Need to pick and choose, I don't have any specific selection right now.

[shcheklein]

@efiop so, is the idea to go through all existing PRs? (from all contributors?)

[efiop]

@shcheklein All unmerged ones at least.

[shcheklein]

@efiop will take a look if some of them are useful

[shcheklein]

Merged googlearchive/PyDrive#185 and googlearchive/PyDrive#184 (direct into master since it's an obvious change)

[shcheklein]

Have checked all PRs - most of them are merged (as well as we fixed a lot of stuff from the active forks) - created separate tickets for those that are not merged - they are not ready, need tests, some of them depend on each other, etc. Might fix some of those when I have time or we can wait for contributors to come to us - we'll be way more responsive. Closing this generic ticket for now.
