Bump mergo v0.3.8

[zappy-shu]

- What I did

Bumps mergo from v0.3.7 to v0.3.8

full diff: imdario/[email protected]

includes:

• Add strict override darccio/mergo#112 Add strict override
  • fixes WithOverride should be able to check types darccio/mergo#111 WithOverride should be able to check types
• Fix merging of interface types with concrete values darccio/mergo#106 Fix merging of interface types with concrete values
• should not overwrite pointers directly, instead check embedded values… darccio/mergo#120 should not overwrite pointers directly, instead check embedded values
  • fixes Embedded struct of pointer types will overwrite the whole destination struct darccio/mergo#114 Embedded struct of pointer types will overwrite the whole destination struct
• added WithOverrideEmptySlice config flag darccio/mergo#125 added WithOverrideEmptySlice config flag

- How I did it

Updated the vendor and added 2 special transforms to handle a change in how pointers in maps are handled in mergo: darccio/mergo@v0.3.7...v0.3.8#diff-a103b5fee5fb31abebf12ee067c01da8R153

These transforms ensure that:

• ulimit config overrides correctly switch between single and soft/hard instead of merging the 2 together.
• service network config aliases are replaced with the override list instead of the lists being appended.

- How to verify it

The existing unit tests cover the special transforms as they have been put in place to preserve the existing functionality

- Description for the changelog

Bumps mergo dependency from v0.3.7 to v0.3.8

The linter is complaining 🦁

cli/compose/loader/merge.go:206:49: mergeUlimitsConfig - result 0 (error) is always nil (unparam)
func mergeUlimitsConfig(dst, src reflect.Value) error {
                                                ^

func mergeServiceNetworkConfig(dst, src reflect.Value) error {

@zappy-shu I know the bump breaks some tests in the cli and you added those 2 transform functions to fix it, but as the code is not that trivial to review and obviously to refactor too, do you think we could add specific tests cases on this part?
