This commit adds SSA merge strategy markers that allow the API server to
granularly merge lists, rather than atomically replacing them. Composition
functions use SSA, so this change means that a function can return only the list
elements it desires (e.g. tags) and those elements will be merged into any
existing elements, without replacing them.

For the moment I've only covered two cases:

* Lists that we know are sets of scalar values (generated from Terraform sets)
* Maps of scalar values (generated from Terraform maps)

I'm hopeful that in both of these cases it _should_ be possible to allow the map
or set to be granularly merged, not atomically replaced.

…error-type

Ignore specific error that returned by expandWildcard function

in external-client's Create even if the returned diagnostics contain
errors.

- In most cases, the Terraform plugin SDK's create implementation
  for a resource comprises multiple steps (with the creation of
  the external resource being the very first step). In case, the
  creation succeeds but any of the subsequent steps fail, then
  upjet's TF plugin SDK-based external client will not record
  this state losing the only opportunity to associate the MR
  with the newly provisioned external resource in some cases.
  We now put this initial state into the upjet's in-memory
  state cache so that it's now available for the external-
  client's next observe call.
