feat!: expedited proposal min deposit param (#254)

* make proto-all * make proto-all with IsExpedited flag * expedited_voting_period on voting params * go mod tidy * add IsExpedited flag to all proposals * implement the foundation for expedited proposals * add validation for voting period params * validate tally params - expedited must be greater than or equal to regular tally * fix cli * fix problems with querying tally params * TestProposalPassedEndblocker for expedited * update TestCmdParams * fix TestMigrate v040 * fix TestGRPCQueryProposal * fix v043 TestMigrateJSON * fix TestRandomizedGenState * fix TestSimulateMsgSubmitProposal * TestExpeditedToRegularConversion * fix TestIntegrationTestSuite/TestCmdParams/text_output * test TestExpeditedProposal_PassAndConversionToRegular * attempt to fix TestAppStateDeterminism * fix TestRandomizedGenState after changing rand generation bounds * fix TestParamChanges * Update x/gov/abci.go * Update x/gov/abci.go * Update x/gov/types/keys.go * refactor to have isExpedited flag on the proposal struct * fix tests * clean up proto files and remove is_expedited from CommunityPoolSpendProposal * fix migrate tests * fix proto * Update x/gov/abci.go Co-authored-by: Aleksandr Bezobchuk <alexanderbez@users.noreply.github.com> * Update proto/cosmos/gov/v1beta1/gov.proto Co-authored-by: Aleksandr Bezobchuk <alexanderbez@users.noreply.github.com> * expedited vote threshold must be strictly greater than regular * fix Cmd tests * fix another cmd test * Add spec for emergency voting (#249) * Add simple changelog * Update x/gov/spec/01_concepts.md Co-authored-by: Aleksandr Bezobchuk <alexanderbez@users.noreply.github.com> Co-authored-by: Aleksandr Bezobchuk <alexanderbez@users.noreply.github.com> * Update x/gov/types/keys.go Co-authored-by: Matt, Park <45252226+mattverse@users.noreply.github.com> * remove redundant isExpedited flag from ContentFromProposalType * Update x/gov/abci.go Co-authored-by: Matt, Park <45252226+mattverse@users.noreply.github.com> * feat: expedited proposal min deposit param * fix TestMigrateJSON * improve TestProposalHandler to test validation of invalid min expedited deposit param * fix abci tests * fix migrate_test.go * fix more cli tests * fix TestRandomizedGenState * fix merge issue * Update x/gov/types/proposal.go * Update x/gov/abci_test.go Co-authored-by: Matt, Park <45252226+mattverse@users.noreply.github.com> Co-authored-by: Aleksandr Bezobchuk <alexanderbez@users.noreply.github.com> Co-authored-by: Matt, Park <45252226+mattverse@users.noreply.github.com>
