Releasing v0.15.0

[CommanderStorm]

Hi @nyurik @sharkAndshark
Quick check in if the current state would be a good place to do a release or if something has to be finished first (we have not done one in some time => lets not leave too many features "in limbo").

I went through the commits and came up with the following. What do you think? ^^
The list is ordered somewhat by how important I think they are => please feel free to reorder

[nyurik]

you read my mind :)

Lets do one last bump of dependencies (using cargo update), and publish. @CommanderStorm want to do the honors?

[nyurik]

P.S. note that some updates might break, so we may want to keep back on those. Lets bump everything that's easy to bump

[sharkAndshark]

We really should do a new release

[nyurik]

my only concern is that we no longer have a stable ci :(

[nyurik]

@CommanderStorm we don't have to wait for CI stabilization to release, but that also means we may need to comment out the failing tests in the meantime

Besides being able to ship additional features, a new release (at least) every few months is also good for security reasons, as it ensures that the binaries are built with the latest compiler (which may include fixes/improvements) and that the Docker container also includes the latest security patches.
