[GRIN-Node] Choose a different default directory for grin blockchain storage

[MCM-Mike]

Description:
Choose a different path for storing the GRIN blockchain.

Prerequisites:
Run a GRIN-Node and make changes the following changes to you grin-server.toml:

grin-server.toml

#the directory, relative to current, in which the grin blockchain
#is stored
d_root = "/some/other/path"

Expected result:
After the GRIN-Node is fully synced all related GRIN blockchain files should be in the specified folder.
Example:

lrwxrwxrwx 1 grin grin        40 Apr 22  2020 grin 
-rw-r--r-- 1 grin grin         0 Apr 22  2020 grin.lock
-rw-r--r-- 1 grin grin      7905 Nov 10 10:10 grin-server.toml
drwx------ 4 grin grin      4096 Jan 15  2019 header
drwx------ 2 grin grin      4096 Jan 15  2019 lmdb
drwxr-xr-x 2 grin grin      4096 Apr 22  2020 peer
drwx------ 5 grin grin     4096 Jan 15  2019 txhashset
-rw-r--r-- 1 grin grin 831392297 Dez 11 17:40 txhashset_snapshot_0004fa3384d3.zip

I have tested version grin-5.0.0-beta.3 on windows 10 Home (1903)
I have first run grin to generate server-toml then edited d_root
d_root = "C:\GrinTest"
I run and sync node successfully. Node is synced fully.

Following files are generated in folder "C:\GrinTest"

• header (folder)
• Imdb (folder)
• peer (folder)
• txhashset (file)

Following files are in default location C:\Users\username.grin\main

• chain_data (folder)
• .api_secret (file)
• .foreign_api_secret (file)
• grin-server.log (file)
• grin-server.toml

Some of the folders stated in "Expected results" are missing in specified folder.

Good work @cekickafa ! Could you copy paste some terminal outputs? I think on Windows you can list content of directory with ‘dir’ command.

also, could you list which folders are missing? Or better provide a terminal output that shows they are missing

Content of folder in modified path (C:\GrinTest)

               6 Dir(s)  121.486.356.480 bytes free

These are the missing files/folders:
