Add layer max cores

[akim-ruslanov]

Link the Issue(s) this Pull Request is related to.
Currently, the SET_ALL_RENDER_LAYER_CORES filter action only affects the layer's min cores. This can be improved since in some cases setting only min cores or max cores is more beneficial.

Summarize your change.
Changes SET_ALL_RENDER_LAYER_CORES to SET_ALL_RENDER_MIN_CORES and SET_ALL_RENDER_MAX_CORES which allows to set only max cores and/or min cores per layer.

Previous PR was closed due to CLA issues.

Regarding the comments, the minor version was changed in order to represent changes to proto.

No comments on the code.

Please add more context to the PR description mentioning the field already existed and is already part of the dispatchQuery, the only missing part is the ability to update it. While reviewing I was questioning if the newly added int_cores_max was already part of the layer table because I don't see changes to the db schema.

int_cores_max is already part of the layer table as can be seen in V1__Initial_schema.sql

Change LGTM, just one minor comment about the proto file, and please resolve that conflict with VERSION.in (but make sure this PR still increments the minor version after the conflict is resolved).
