Since Postgres commit da9b580d files and directories are supposed to
be created with pg_file_create_mode and pg_dir_create_mode permissions
when default permissions are expected.
This fixes a failure of one of the postgres tests:
If we create file add.conf containing
```
shared_preload_libraries='citus'
```
and run postgres tests
```
TEMP_CONFIG=/path/to/add.conf make installcheck -C src/bin/pg_ctl/
```
then 001_start_stop.pl fails with
```
.../data/base/pgsql_job_cache mode must be 0750
```
in the log.
In passing this also stops creating directories that we haven't used
since Citus 7.4
This change explicitely doesn't change permissions of certificates/keys
that we create.

The file handling the utility functions (DDL) for citus organically grew over time and became unreasonably large. This refactor takes that file and refactored the functionality into separate files per command. Initially modeled after the directory and file layout that can be found in postgres.
Although the size of the change is quite big there are barely any code changes. Only one two functions have been added for readability purposes:
- PostProcessIndexStmt which is extracted from PostProcessUtility
- PostProcessAlterTableStmt which is extracted from multi_ProcessUtility
A README.md has been added to `src/backend/distributed/commands` describing the contents of the module and every file in the module.
We need more documentation around the overloading of the COPY command, for now the boilerplate has been added for people with better knowledge to fill out.
