Automatic collection generation

[andremacedopv]

• Create script in the chaincode main package to generate the collections.json file
  • The script is only executed if the -g flag is used
  • The --orgs/-o can be used to pass a list of organizations to be considered when generating the policy
  • The scripts adds the collections according to asset types with readers and the number of orgs being deployed
• Removed collection files (and added it to gitignore)
• Added collection generation to startDev and upgradeCC scripts
• Created a generateCollection.sh script just to generate the collections.json file
  • The script can take multiple -o argumets to determinate the orgs to be considered on the generation
• Updated the generateTar.sh script to generate the collections.json file
  • The script can take multiple -o argumets to determinate the orgs to be considered on the generation
• Unrelated to the collections, this PR also features a small fix to the generateTar.sh script so it includes hidden files (such as .env) when compressing the go ccapi
