satellite/nodeselection: SelectBySubnet should use placement filters for all nodes
Current node selection logic (in case of using SelectBySubnet):

 1. selects one subnet randomly
 2. selects one node randomly from the subnet
 3. applies the placement NodeFilters to the node and ignore it, if doesn't match

This logic is wrong:

 1. Imagine that we have a subnet with two DE and one GB nodes.
 2. We would like to select DE nodes
 2. In case of GB node is selected (randomly) in step2, step3 will ignore the subnet, even if there are good (DE) nodes in there.

satellite: move satellite/nodeselection/uploadselection => satellite/nodeselection
All the files in uploadselection are (in fact) related to generic node selection, and used not only for upload,
but for download, repair, etc...

d2033c2f52 satellite/nodeselection/uploadselection: rename package
Currently nodeselection package only contained state for uploads, move
these to a subpackage, such that we can make another "downloadselection"
for downloads. Then move selection logic from overlay to nodeselection.

08692aef90 satellite/nodeselection: node selection with proper bias
Currently node selection cache is biased towards the same subnet. This
implements static node selection for distinct such that it selects with
equal probability subnets rather than id-s.

This is mostly a copy paste + modifications from previous node selection
state.
