Fix: Adding min threshold and duration for dao motion

[sameh-farouk]

Description

• What does this PR do?

  • Adding a minimum for the threshold (5) that the user provide when submitting a Dao proposal
  • Adding a minimum for the duration (1 day) that the user may provide when submitting a Dao proposal
  • Update Docs
  • Update and adding relevant tests

• Why are these changes needed?

  • A low threshold with a short voting time could result in a proposal passing without farmers even knowing that the proposal took place.

• How were these changes implemented and what do they affect?

  • These changes affected the creation of new Dao proposals and required tighter rules for threshold and duration.

Related Issues:

• Any council member can take action without the support of other members/farmers #889
